A highly integrated Multifunction Temperature Calibrator featuring several patented technologies, the 221A is an ultra-compact, rugged, and easy to use hand-held device for sourcing, simulating and measuring temperature, and electrical signals. Its smartphone-like menu and interface make the operation simpler and easier. The 221A is ideal for calibrating, maintaining, and troubleshooting process instrumentations. Automation and documentation capabilities make the 221A a turnkey solution.
Sourcing, simulating and measuring temperature and electrical
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 Additel 160A
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 handed operation
Calibrated cold junction compensation (Patented)
Cold junction equalizing block in the calibrator
A calibrated PRT element with flexible leads is
in the equalizing block for thermocouple cold junction
This PRT element can be pulled out from the calibrator
and re-calibrated and corrected at the ice point
Documenting and automated procedure capability
Manage the information of the device under test.
Set up automated calibration procedures, and 223A
performs the test, calculates the errors, displays and/
or stores the results in the memory, and highlights the
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 data.
ISO 17025 accredited calibration with data
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)
Build-in unit conversion tool
Build-in converters for pressure units, temperature
units, temperature vs. resistance (RTDs), and
temperature vs millivolt (thermocouples)
Warranty: 3 years
HART Communication capability (223A)
3.5 inch TFT color screen
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 Li-ion battery for 15 hours uninterrupted
Battery life will be reduced when 24 V is applied.
The rechargeable battery is replaceable.
