A highly integrated Multifunction Temperature Calibrator featuring several patented technologies, the 221A is an ultra-compact, r ed, 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 simple. The 221A is ideal for calibrating, maintaining, and troubleshooting process instrumentation. Automation and documentation capabilities make the 221A a turnkey solution.
FEATURES:
- 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
24V loop power supply
Simultaneous dual reading capability
Automatic switch test
Supports square root transmitter
Pulse frequency output for the calibration of flow
totalizer
Smartphone-like menu and interface make the
operation simpler and easier
Ultra-compact, size 3.9" x 7.6" x 2.0" (100mm x 192mmx 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.
