Ultra-compact, size 3.9” x 7.6” x 2.0” (100mm x 192mm x 52mm), and weight 1.6 lb (0.7 kg)
One hand operation

Calibrated cold junction compensation (Patented)

Cold junction equivalent block in the calibrator
A calibrated PRT element with flexible leads is installed in the equivalent block for thermocouple cold junction compensation
This PRT element can be pulled out from the calibrator and re-calibrated and corrected at ice point by users

Built-in temperature readout

CVD coefficients of a calibrated PRT can be input into the calibrator for accurate temperature measurement

Multi lingual interface

English, German, French, Italian, Spanish, Portuguese, Simplified Chinese (Traditional Chinese, Japanese and Russian are available per request)

Documenting and automated procedure capability

Manage the information of the device under test.
Set up automated calibration procedures, and ADT 221A performs the test, calculates the errors, displays and/or stores the results in the memory, and highlights the out-of-tolerance points.
As-found and As-left functions allow recording and documenting results for quality control.
Download tasks and upload the results.
Snapshots allow you to capture and save work.

Build-in unit conversion tool

Build-in converters for pressure units, temperature units, temperature vs. resistance (RTDs), and temperature vs millivolt (thermocouples)

Display 3.5 inch TFT color screen

Rugged design for harsh environments.
Passed a 1-meter drop test.
Three year warranty for the 221A, and one year for the battery pack

Misuse protection

Up to 30V voltage on any two sockets and up to 1A current on current sockets will not damage the calibrator.
The calibrator will return to normal condition as soon as the voltage or current is removed.

Rechargeable battery
