Additel’s new 875 series Dry Well Calibrators are real game changers in portable temperature calibration.

Additel’s new ADT875 Dry Well Calibrator series provides portability, ruggedness, and precision over a wide temperature range, combining excellent performance in stability, radial and axial uniformity, and loading with speed.

The ADT875 Dry Well Calibrator series consists of three temperature ranges from –40°C to 660°C:
– Low temperature –40C° to 155°C (ADT875-155)
– Mid-temperature 33°C to 350°C (ADT875-350)
– High temperature 33°C to 660°C (ADT875-660)
Each unit has performance specifications related to the guidelines published in Euramet cg-13 specifying stability, radial and axial uniformity, loading, and hysteresis.

Features
• Three models ranging from -40°C to 660°C
• Portable, rugged, and quick to temperature
• Metrology-level performance in stability, uniformity, accuracy and loading effect
• Dual-zone control
• Process calibrator option provides a multi-channel readout for a reference 
thermometer, RTDs and
TCs, task documentation, and HART communication
• Colour touch screen display

A Process Calibrator option adds the capabilities of a three-channel thermometer readout and a documenting process calibrator, combining many of the features found in a HART documenting process calibrator with the temperature dry well. This option includes the ability to measure a reference PRT and two device under test channels which can measure, mA, voltage, switch, RTD or thermocouple. In addition to these measurement functions, this calibrator has documenting capability of creating tasks, saving as found and as left results, and HART communication.
