We are taking temperature calibration to the next level with the Additel 878 Reference Dry Well Calibrators.

Additel introduces their new ADT878 Reference Dry Well Calibrator series which consist of three products that combine to cover a temperature range from –40°C to 700°C. The Additel Reference Dry Wells are designed with laboratory-level performance in accuracy, stability, uniformity, loading and hysteresis and combine automation features to automatically realize and maintain a triple point of water cell and facilitate annealing PRTs. Each unit has a process calibration option which includes a full HART communicator, measurement of a reference PRT and two devices under test that can measure mA, V, switch, RTD or thermocouple. In addition to these functions, this calibrator can create and store tasks and document the “as found” and “as left” results.

There are three ranges to choose from: low temperature –40C° to 160°C (ADT878-160), mid-temperature 33°C to 425°C (ADT878-425), and high temperature 33°C to 700°C (ADT878-700). Each unit has performance specifications related to the guidelines published in Euramet cg-13 specifying stability, radial and axial uniformity, loading, and hysteresis.

We are certain that you will be blown away by the outstanding performance of these game-changing Reference Dry Wells!
