Calibration Bath Fluids

sku Product SKU:  FCL-Calibration Bath Fluids

Fluke Calibration carries a full line of bath fluids covering temperature ranges from –100°C to 550°C.

Finally, there’s a convenient source for small quantities of bath fluids for any temperature range. Why pay for more than you need?

Viscosity, volatility and other properties that change with temperature affect the performance of fluids in controlled baths and circulators. Fluke Calibration has tested and used each of the fluids we sell. Over the ranges recommended in the following table, each fluid remains at a low enough viscosity to be adequately pumped or stirred. Whether your application is industrial or critical lab calibration work, Hart fluids give you top performance and stability.

For temperature ranges too high for oils, we have a bath salt with a viscosity in the molten state similar to the viscosity of water. For your convenience, it is shipped in a granular form, making it easy to fill your bath.

Between its melting point of 150°C and 550°C, this salt has the highest temperature stability and uniformity available in a bath fluid. It does not smoke like oils or give off dust like “sand" or fluidized alumina baths. Check with your bath manufacturer before using this salt to make sure your equipment is compatible. Fluke Calibration offers three standard bath models and custom-designed units for use with this salt.

Fluid specifications 
It’s important to understand a few specifications before selecting a bath fluid. We’ve seen bath fluids advertised with a temperature range that spans from the freezing point to the flash point or beyond.

For example, type 710 silicone oil has a freezing point of –22°C, but freezing point has nothing to do with the point at which the oil becomes so thick it cannot be properly stirred. Type 710 oil should really only be used down to about 80°C. It’s a viscosity issue, not a freezing-point issue. Usable range is the question. Suitability for calibration work is the specification that counts.

The usable viscosity range is determined by your bath’s stirring or pumping design. Fluke Calibration baths can be operated using fluids with up to 50 centistokes viscosity. This gives you additional usable range in the lower temperature levels of the fluid.

Some baths advertised as calibration baths require fluids with 10 centistokes or less viscosity to operate properly. The usable ranges in our table on the previous page assume the use of a Fluke bath.

In addition to range and viscosity issues, there are a number of other issues to consider when choosing a bath fluid. The other considerations are:

  • Thermal characteristics
  • Lifetime
  • Change in characteristics due to temperature cycling
  • Absorption of water from the air
  • Vaporization—fumes and fume hood requirements
  • Expansion due to heat
  • Contamination—mixing oils or introducing contamination with unclean probes
  • Conductivity properties
  • Effects of using fluids outside of their range—fire, explosion, polymerization
  • Effects of altitude on boiling point

    Custom Temperature Calibration Baths

    sku Product SKU:  FCL-Custom Temperatures Calibration Baths

    Fluke Calibration temperature baths provide optimal temperature environments for “secondary” or “comparison” temperature calibrations. They offer unsurpassed stability and uniformity, a large working volume, and flexibility for performing thermometer calibration on calibrating a variety of temperature sensors. However, if your needs aren’t met by our standard sizes and temperature ranges, then we can build a custom bath that is as reliable and as fine a calibration instrument as any standard bath we manufacture.

    Some of the examples of the custom baths we have built include significant bath tank changes (taller, wider or deeper), change in the temperature range, different height or particular shape, faster heat and cool rates. We have built baths that require windows or custom dimensions to accommodate test fixtures. We can do all of this and more. No other manufacturer supplies custom baths to their customers, but we do.

    Our engineers and designers know more about temperature calibration baths than anyone else. You’ll find our baths throughout the best national and international temperature calibration labs. It does not matter what type of calibration application you have – oceanography, missile optics, infrared, sensor manufacturing, semiconductor, renewable energy, LIG manufacturing, or down-hole tools. We have probably already built baths to do the job.

    sku Product SKU:  FCAL-9142-3-4

    Product overview: Fluke Calibration 9142 Field Metrology Well

    Small dry wells for big field applications

    The 9142, 9143, 9144 Field Metrology Wells extend high performance to the industrial process environment by maximizing portability, speed, and functionality with little compromise to metrology performance.

    Field Metrology Wells are packed with functionality and are remarkably easy to use. They are lightweight, small, and quick to reach temperature set points, yet they are stable, uniform, and accurate. These industrial temperature loop calibrators are perfect for performing transmitter loop calibrations, comparison calibrations, or simple checks of thermocouple sensors. With the “process” option, there is no need to carry additional tools into the field. This optional built-in two-channel readout reads resistance, voltage, and 4–20 mA current with 24 volt loop power. It also has on-board automation and documentation. Combined, the three models (9142, 9143, and 9144—each with a “process” option) cover the wide range of –25 °C to 660 °C.

    High performance for the industrial environment

    Field Metrology Wells are designed for the industrial process environment and fast speed to temperature. They weigh less than 8.2 kg (18 lb) and have a small footprint, which makes them easy to transport.

    Field environment conditions are typically unstable, having wide temperature variations. Each Field Metrology Well has a built-in gradient-temperature compensation (patent pending) that adjusts control characteristics to ensure stable performance in unstable environments. In fact, all specifications are guaranteed over the environmental range of 13 °C to 33 °C.
