We are taking temperature calibration to the next level with the Additel 878 Reference Dry Well Calibrators. Additel’s commitment to continuous improvement, quality and time saving features are on full display in the ADT878 series. With three models to choose from, ranging from -40 to 700°C, you will find the perfect fit for your calibration needs. The Process Calibrator option adds an external reference input, a two-channel readout for UUT’s and a full complement of capabilities to help with everything from measuring temperature sensors, to calibrating thermocouples, self-calibrating the Reference Well and configuring HART transmitters. Each unit comes standard with a large touchscreen display, dual-zone control and Additel’s commitment to the best customer service in the industry. We are certain that you will be blown away by the outstanding performance of these game-changing Reference Dry Wells!

Process Calibrator Option
Each model can be purchased with our Process Calibrator (PC) option. This option combines the many features found in a fully functional HART documenting process calibrator with the reference grade dry well. This option includes the ability to measure a reference PRT, with virtually any connection type, and two device under test channels which can measure, mA, voltage, switch, RTD or thermocouple. In addition to these measurement functions, this calibrator has full documenting capability of creating tasks, saving as found and as left results, as well as communication with HARTsmart transmitters. The process calibrator option also has an on board full HART communicator which allows users to read, configure and calibrate HART transmitters. The snap shot feature allows you to capture all information displayed on the screen with the push of a button. This optional add-on allows for data logging of all channels on an auto step function. Using a reference PRT, you can also control to the dry well set point using either the internal sensor or an external reference PRT.
