Additel Temperature Calibrators Additel 878 Series

Additel 878 Temperature Calibrators 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.

Additel Corporation is one of the leading worldwide providers of process calibration tools. We are dedicated to designing, manufacturing, and delivering the highest quality handheld test tools and portable calibrators for process and calibration industries. For many years Additel has successfully developed automated pressure calibrators, digital pressure test gauges, digital pressure calibrators, pressure test and calibration pumps, and multifunction process calibrators.

Additel 878 Temperature Calibrators Series

We are taking calibration to the next level with the Additel 878 Series Reference Dry Well Calibrators. Additel’s commitment to continuous improvement, quality, and time-saving features are on full display in the ADT878 series.

With Temperature Calibrators Additel 878 Series, 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.

Temperature Calibrators Additel 878 Series comes standard with a large touchscreen display, dual-zone control, and Additel’s commitment to the best customer service in the industry.

Process Calibrator Option

This option includes the ability to measure a reference PRT, with virtually any connection type, and two devices under test channels that can measure, mA, voltage, switch, RTD, or thermocouple. In addition to these measurement functions, this calibrator has the full documenting capability of creating tasks, saving as found and as left results, as well as communicating with HARTsmart transmitters.

The process calibrator option also has an onboard full HART communicator which allows users to read, configure and calibrate HART transmitters. The snapshot 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.  By utilizing the reference PRT, you can select to control the dry well setpoint using the internal sensor or the external reference PRT.
