Additel ADT878 Reference Dry Well Calibrator

The Additel ADT878 Reference Dry Well Calibrator is a portable calibrator with temperature ranges from -40 to 1292°F. It has a two-channel readout, HART & self-calibration feature. There are three models to choose from in the Additel ADT878 series, ranging from -40 to 700C. The ProcessCalibrator option adds external reference input, two channels of UUT reading and a full complement of capabilities to help with everything from calibrating temperature sensors to measuring thermocouples, setting up HART transmitters or configuring the Reference Well.

A large touchscreen display, two-zone control and Additel’s dedication to the best customer service in the industry will all be included with each unit. Full HART communicators are also available on the process calibrator option, which enables users to read, set up and calibrate HART transmitters. All information on the screen can be captured by pressing a button with this snapshot feature.

The Additel ADT878 data logging of all channels by using the auto step function is allowed by free add-on. You may also use the Internal Sensor and an External Reference PRT to monitor the Dry Well Setting Point. In Additel’s view, the best method of setting your temperature is to use an outside reference probe as a standard. However, they are aware that this approach may not be required or practicable in certain situations and therefore prefer to use an internal control sensor.
