Liquid Trap

sku Product SKU:  FCL-Liquid Trap

The 7000-102 Liquid Trap can be used with most any pneumatic test or calibration system where liquid contamination may be present in the device under test. Although the preferred procedure is to insure the device under test is free of both liquid and particulate contamination prior to calibration, the 7000-102 provides a degree of insurance to protect the calibration instrument.

The 7000-102 can be used with any calibrator, including the Model 7010 and complete line of Series 7215 Digital Pressure Controllers. It can assist with minimizing the possibility of contamination of the unique Ruska quartz sensor found in these instruments along with the control valves and solenoid valves, all of which are designed for pneumatic operation and can be damaged when exposed to liquids.  

The 7000-102 is also compatible with Druck’s line of pressure controllers including the DPI 515 and DPI 520 Digital Pressure Calibrators.

Further, the 7000-102 can be used with virtually any test or calibration system where the pressure does not exceed 3000 psi. 

A convenient drain valve allows periodic removal of accumulated liquids. Due to the pressure range, the level inside the Trap cannot be observed. Therefore it is recommended that the drain valve be opened on a frequent basis or prior to each test. A fitting is provided on the drain valve to allow connection to tubing that can run to a container for disposal.

The 7000-102 Liquid Trap is provided with a bench mount stand with two mounting holes for a sturdy installation.

Fluke Calibration 155X Stik Thermometer

sku Product SKU:  FCAL-155X Stik

Finally, a digital substitute for your mercury-in-glass thermometers! Accurate and repeatable to ± 0.05 °C over its full range, the 1551A/1552A “Stik Thermometer is the new “gold standard" of industrial temperature calibration. Whether working outdoors in environments where potentially explosive gases may be present or on the floor of a processing plant, the intrinsically-safe, battery operated, portable reference thermometer is designed to go where you work.

Features at a glance

  • Accuracy of ± 0.05 °C (± 0.09 °F) over full range
  • Intrinsically safe (ATEX and IECEx compliant)
  • Two models to choose from (-50 °C to 160 °C or -80 °C to 300 °C)
  • User-configurable temperature Trend/Stability indicator
  • Display temperature in °C or °F
  • Optional data logging to internal memory
  • 300-hour battery life
  • Percent battery-life and low-battery indicator
  • NVLAP-accredited, NIST-traceable calibration included

Thermometer probe and digital readout combined into one unit

The stainless steel probe and digital readout are fixed together and calibrated as a system. The accuracy specification is easy to understand since it includes all uncertainty components, including drift, for up to one year1. The large backlit LCD display rotates 90° degrees making it easy to read from any angle. A user-configurable stability/trend indicator lets you know when your temperature is stable enough to record an accurate measurement. A user-settable auto-off function extends typical battery life to three hundred hours. A low-battery indicator and stop-measure function prevent erroneous measurements from being made due to low battery life. A simple three-point calibration function allows you to easily and accurately calibrate the “Stik" Thermometer. Data logging to internal memory of up to 10,000 time-stamped measurements is optionally available.

Why calibrate process temperature sensors?

Because temperature greatly effects the accuracy of a volumetric measurement, process manufacturers of chemical, pharmaceutical, food or petroleum products require accurate temperature measurements—especially for processes where quality or custody transfer are regulated by government agencies. Since all temperature sensors are subject to drift with time, regular calibration or verification against a reliable reference thermometer is required. Finding a reference thermometer that is accurate, repeatable and robust, however, can be challenging.

What’s wrong with my reference thermometer?

Industrial reference thermometers available on the market today, such as mercury-in-glass thermometers (or “ASTM thermometers") and portable electronic thermometers are useful, but both come with inherent problems. Although accurate and repeatable, mercury thermometers are fragile. The risk of a mercury spill poses potential hazards to the environment and to the health of personnel. Many of the United States and European Union countries have already banned their use in industrial applications. Some organizations have replaced their mercury thermometers with more durable portable electronic thermometers, only to discover that the RTD probes lack the repeatability and dependability required of a legitimate reference thermometer.

The best alternative to mercury thermometers

The Fluke “Stik" Thermometer is accurate, stable and durable, making it the best alternative to mercury thermometers and existing electronic thermometers. The thin-film RTD sensor incorporates the same characteristics of other premium reference thermometers designed by Hart Scientific, but it is more robust and less susceptible to drift. Accuracy and repeatability, however, are not sacrificed for improved durability.

Using a glass-stem mercury- or spirit-filled thermometer at different immersion depths, or at significantly different ambient temperatures from which it was calibrated, may require the application of emergent-stem corrections that can be tedious but necessary to calculate an accurate measurement. This isn’t required with the “Stik" Thermometer. The sensor of the 1551A Ex requires a minimum immersion depth of only seven centimeters (2.8 inches), with no appreciable effect on the measured temperature due to heat loss through stem conduction. Some digital thermometers can become less accurate when used outside a narrow range of ambient temperatures. This isn’t the case for the “Stik" Thermometer. Your measurement remains accurate in ambient temperatures from -10 degrees to 50 degrees celsius (14 degrees to 122 degrees fahrenheit). With a superior probe design combined with electronic functions that assist accurate measurement, the “Stik" Thermometer surpasses the capabilities of other digital thermometers and is the perfect substitute for your mercury thermometers. 1In order to minimize sensor drift, the probe should always be protected from mechanical shock.

Five reasons to replace mercury thermometers

  1. Since the “Stik" Thermometer does not contain mercury, it is not subject to government-imposed bans. Government agencies worldwide have either banned or are seeking to ban the use and transportation of industrial mercury thermometers—this seems to be a growing trend.
  2. The stainless steel probe sheath of the “Stik" Thermometer is far more robust than the glass stem of a mercury thermometer and better suited for industrial environments. And since the “Stik" thermometer does not contain mercury, the risk of an accidental mercury spill is eliminated.
  3. When considering cost of ownership, a digital thermometer is less expensive than a mercury thermometer. With a mercury thermometer, you either invest in equipment or you hire out to clean up after a mercury spill.
  4. Mercury thermometers cannot be adjusted after calibration. The actual temperature must be calculated by applying corrections to the measured temperature. This costs time and is susceptible to calculation error. A digital thermometer does the math for you—the displayed temperature accurately represents the actual measured temperature.
  5. Emergent-stem corrections may also be required if the mercury thermometer is not used under the same conditions under which it was calibrated. A digital thermometer doesn’t require that you match calibration conditions to achieve an accurate measurement. You’re only required to meet the minimum immersion requirements—which is only seven centimeters (2.8 inches) in the case of the 1551A Ex.

Fluke 8588A Reference Multimeter

sku Product SKU:  FCAL-8588A

Stability, simplicity, and performance by design

The 8588A incorporates exceptional linearity, low noise, and stability in the design. This best-in-class long-scale digital reference multimeter guarantees superior 3.5 ppm one-year dc voltage relative accuracy and long-term stability over a wide measurement range and functions.

The 8588A contains the world’s most stable voltage references and attenuators custom crafted at Fluke Calibration.  These precision components eliminate the need for daily internal self-calibration to compensate for drift when less-precise components are used.  Autozeroing also becomes unnecessary because the amplifier offsets are ultra-stable.  The 8588A achieves an exceptional 8.5-digit resolution reading in one second, two times shorter than the next best in class, which amounts to considerable productivity improvements.

The 8588A is easy and intuitive to use. It is the ideal lab multimeter for metrologists and calibration laboratory managers who expect and appreciate a straightforward setup that quickly achieves the maximum performance of the instrument.

  • 2.7 µV/V (95%), 3.5 µV/V (99%), 1 year relative accuracy, dc voltage without internal self-calibration or auto-adjustments
  • 0.5 µV/V (95%), 0.65 µV/V (99%), 24 hour stability, dc voltage
  • 7 µΩ/Ω (95%), 9 µΩ/Ω (99%), 1 year, resistance
  • 2.02x full scale stretches lower noise floor to higher signal levels to maximize higher accuracies from the instrument
  • 200 ns to 100 s aperture setting allows the industry's widest flexibility to control data capture window

Accuracy, offset and stability provide excellent ac performance

The 8588A provides the most accurate true ac rms measurement available in a Fluke Calibration multimeter.

With a 5 mega-samples-per-second sampling analog-to-digital converter and an extraordinarily stable dc analog path, the 8588A achieves remarkable ac rms measurement performance that is ten times faster, two times less noisy, and more sensitive for low level signals than other instruments in this class. It utilizes digital rms calculations to maintain full resolution of a wide dynamic range of digitized signals, so you can see a wide range of measurements clearly.

Rapid digital filters are more effective than their analog equivalents for faster settling. The digital filters eliminate the dielectric absorption on analog filters, commonly associated with residual slow-tail characteristics. The digital filters effectively shorten settling time to within 6 cycles of the filter frequency and less than 1 ppm of the fully settled value.This is up to 10 times faster than other long scale precision digital multimeters at low frequencies.

Low noise is achieved from averaging the collected high-resolution digitized data and the inherently stable signal path. De-coupling low level signal sensitivity from temperature drift enables the 8588A to make higher accuracy low-level ac measurements. Therefore, temperature drift, offsets, and long-term instability typically associated with an analog rms converter are eliminated.

  • 60 µV/V (95%), 77 µV/V (99%), 1 year relative accuracy, for the most accurate ac voltage measurement
  • 250 µA/A (95%), 323 µA/A (99%), 1 year relative accuracy, ac current
  • 15 ms settling time at 1kHz ac filter form 10x faster ac voltage measurement
  • 2.02x full scale Vpp, 1.2x full scale rms
  • Up to 30 A for peak ac current greatly extends ac current measurement range


Usability designed for metrologists by metrologists

The 8588A is the ideal lab multimeter. It streamlines the measurement process while eliminating misunderstandings, with an easy-to-access user interface in English, Chinese, French, German, Japanese, Korean, Russian and Spanish. An intuitive graphical display lets you easily visualize trends, histograms, complex waveforms, and statistics and perform routine metrology tasks quickly. You can perform both real-time and post-capture analysis for short-term and long-term stability, identifying and quantifying drifts, run-around noise, and uncertainty analysis without the need for an external computer or software. You can also quickly visualize post-processed frequency domain signals of fundamental and harmonic amplitude and phase content.

Some popular system multimeters have complex menu structures and unintuitive commands, while others lack any user interface, presenting barriers to training and operation. By contrast, the 8588A/8558A feature an easy to- access configuration menu that makes it easy to train new users.

The front panel features many new usability improvements. Visual Connection Management™ output terminals light up to show which terminals are active, guiding the user to make the correct connections. The handles are over-molded for comfort and easy transport.

USB host ports are placed both on the front and rear of the instrument. Use the ports to export data to external memory devices or simplify firmware updates. For remote communication with a PC, choose from Ethernet, GPIB or USBTMC connectors on the rear panel.

The 8558A/8558A provides full emulation of the Fluke 8508A Reference Multimeter and command compatibility of the Keysight 3458A Digital Multimeter via SCPI commands, making it an ideal replacement for these older instruments.

  • Graphical display that enables instantaneous visualization of trend plot, statistical analysis, histogram and FFT. 
  • GPIB, USBTMC, Ethernet allows industry-standard selection of remote interface. • USB thumb drive enables quick and easy data transfer to PC in .csv format.
  • SCPI compliant commands with 8508A and 3458A emulation mode simplifies and accelerates system upgrade process to 8588A/8558A

Fluke Calibration 5901 Triple Point of Water Cells

sku Product SKU:  FCAL-5901

Must-have, primary temperature standards

  • Easy-to-use, inexpensive standard with uncertainty better than ± 0.0001 °C
  • Four sizes and two shells (glass and quartz) to choose from
  • Isotopic composition of Vienna Standard Mean Ocean Water

The triple point of water (TPW) is not only the most accurate and fundamental temperature standard available, it’s also one of the least expensive and simplest to use.

Water cells are essential!

Triple point of water cells fill four critical purposes. First, they provide the most reliable way to identify unacceptable thermometer drift between calibrations—including immediately after a calibration if the thermometer has been shipped. Interim checks are critical for maintaining confidence in thermometer readings between calibrations. Second, they provide a critical calibration point with unequaled uncertainties.

Third, for users who characterize probes using ratios (that is, they use the ratios of the resistances at various ITS-90 fixed points to the resistance of the thermometer at the triple point of water, indicated by “W"), interim checks at the triple point of water allow for quick and easy updates to the characterizations of critical thermometer standards, which can be used to extend calibration intervals.

And lastly, the triple point of water is where the practical temperature scale (ITS-90) and the thermodynamic temperature scale meet, since the triple point of water is assigned the value 273.16 K (0.01 °C) by the ITS-90 and the Kelvin is defined as 1/273.16 of the thermodynamic temperature of the triple point of water.

Good triple point of water cells contain only pure water and pure water vapor. (There is almost no residual air left in them.) When a portion of the water is frozen correctly and water coexists within the cell in its three phases, the “triple point of water" is realized. Fluke Calibration water cells achieve this temperature with expanded uncertainties of less than 0.0001 °C and reproducibilities within 0.00002 °C.

In simple terms, water cells are made from just glass and water, but there’s much more to it than that!

For starters, that’s not just any water in there.
