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.
