ADT875 Series Dry Block Calibrator

Additel’s New 875 Dry Block Calibrator series Provides Portability, Ruggedness, and Precision Over a Wide Temperature Range

Zedflo along with  Additel Corporation introduces their new ADT875 Dry Block Calibrator series. It consists of three temperature ranges from –40°C to 660°C. There are three ranges to choose from:–40C° to 155°C (ADT875-155), 33°C to 350°C (ADT875-350) and 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.

All Dry Block Calibrator models have a process calibrator option. This combines many features found in a HART documenting process calibrator with the temperature dry block. This option includes the ability to measure a reference PRT and two channels for device under test, which can measure, mA, voltage, switch, RTD or thermocouple. In addition to these measurement functions, this calibrator has documenting capability. This allows creation of tasks, saving as found and as left results, and HART communication.
