Additel ADT878 Dry Well Calibrator has three models to choose from, ranging from -40 to 1292°F. 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.

The Process Calibrator option includes a full HART communicator for transmitter configuration and diagnostics. Each unit comes standard with a large touchscreen display and dual-zone control for enhanced temperature uniformity. Wi-Fi and Bluetooth capabilities enable wireless communication and remote monitoring.

Additional features include Quick-Push connectors for easy sensor connection (with PC Option), set point control by reference for improved accuracy, self-calibration capability, and built-in automatic annealing for the ADT878-700 model to maintain sensor stability over time. The rugged design ensures reliable performance in field and laboratory environments.
