Sourcing, simulating and measuring temperature and electrical signals

        • Sources and measures mV, mA, ohms, RTDs, thermocouples, frequency, and pulses 
        • Simulates and measures 13 thermocouples and 11 RTDs to calibrate transmitters 
        • Measures and sources pressure using 160 series Intelligent Digital Pressure Modules from -15 psi to 10,000 psi (-1 bar to 700 bar) 
        • 24V loop power supply 
        • Simultaneous dual reading capability 
        • Automatic switch test 
        • Supports square root transmitter 
        • Pulse frequency output for the calibration of flow totalizer

Easy to use 

        • Smartphone-like menu and interface make the operation simpler and easier 
        • 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 

        • 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 

        • Rechargeable Li-ion battery for 15 hours uninterrupted use. 
        • Battery life will be reduced when 24V is applied. 
        • The rechargeable battery is replaceable.
