Product Information

The ultimate in resolution and accuracy

With up to 24-bit resolution the ADC-20 and ADC-24 USB data loggers are able to detect small signal changes. Features such as true differential inputs, galvanic isolation and software-selectable sampling rates all contribute to a superior noise-free resolution and ensure that your measurements are reliable and accurate.

PicoLog 6 software – straightforward from the start

All Pico data acquisition products come complete with PicoLog 6. This powerful yet flexible data acquisition software allows you to collect, manipulate, analyze, display and export data.

Designed from the ground up to be intuitive from the outset, PicoLog 6 allows you to set up the logger and start recording with just a few clicks of the mouse, whatever your level of data logging experience.

From here, starting a capture is simple: plug in the logger, add a channel, press Record, and you’re logging! PicoLog 6 also includes a number of additional features to cater for more advanced data logging needs.

Flexible, multichannel data acquisition

Both the ADC-20 and ADC-24 feature true differential inputs for excellent noise rejection. To give you a very flexible system each differential input can also be configured as two single-ended inputs. With up to eight differential or 16 single-ended inputs on the ADC-24, this flexibility gives you complete control on what type of inputs you use. If you require more channels, you can use multiple PicoLog data loggers on the same PC.

With seven bipolar voltage ranges, the ADC-20 and ADC-24 are also flexible enough to be used with a wide range of sensors and signal types. There's also an external terminal board with screw terminals to allow you to quickly connect and disconnect different sensors.

Additionally, the ADC-24 has four configurable digital input/output channels that can be used to control alarms or other devices.

The flexibility of the ADC-20 and ADC-24 allows you to use these precision data loggers as an advanced multichannel data acquisition system with a low cost per channel.

No need for power supplies or batteries

The high-resolution ADC-20 and ADC-24 are powered directly by your PC — eliminating the need for batteries or a separate power supply, and making them ideal when you need a portable data logger.

The answer to your data acquisition needs

High resolution, true differential inputs, galvanic isolation, and selectable sampling rates combine to ensure that your measurements are always precise and accurate. Configurable inputs, digital inputs and outputs, and programmable voltage ranges give you a truly flexible answer to your data acquisition needs.

When you need the ultimate in high resolution and accuracy, the versatile ADC-20 and ADC-24 provide you with a portable answer with the performance and flexibility you need.
