The Additel 875 dry well calibrator features excellent stability, radial uniformity, and axial uniformity in a portable package so you can calibrate RTD and thermocouple probes as well as mA, voltage, and switches in the field. The process control feature combines many features found in a HART documenting process calibrator with temperature dry well. It also provides the ability to utilize an external reference probe eliminating the worry about uncertainties. Innovative heat pipe design provides superior speed to set temperature—achieve ambient to -40°C well under 20 minutes! Self-calibration feature provides a fresh, traceable calibration of the control sensor to ensure accuracy and minimizes down time.

Easily navigate through setup, measurement, and documentation using the large, color touchscreen display. Full documenting capability allows users to create, save tasks, devices under test, and data. Store up to 1000 tasks which store up to 10 results each containing as found and as left data. Use the snapshot feature for screen captures; record auto step and ramp functions. With this single device you can quickly and easily rearrange, configure, and test HART transmitters.

USB A, USB B, RJ45, Wi-fi, and Bluetooth® capabilities make it easy to communicate with the calibrator. View the display remotely using Wi-fi or Bluetooth and the Additel Mobile Link App. Unit comes with one insert that has one 3/8", two 1/4", one 3/16", and one 1/8" diameter holes. When calibrating multiple probes, use the reference probe to achieve better accuracy.
