Product Overview: Pie 322 Thermocouple Calibrator
Fast Thermocouple Calibration with Automatic Output Stepping
Speed up thermocouple calibration with automatic output stepping designed for faster, more efficient testing. The PIECAL 322 lets you choose 2, 3, 5, or 11 step sequences and ramp output automatically in 100%, 50%, 25%, 10%, or 5% of span. Adjustable step times from 5 to 60 seconds make it easy to match your calibration process to your system requirements.
Compatible with Process Instruments and Control Systems
The PIECAL 322 is built for broad process instrument compatibility, making it an ideal thermocouple calibrator for transmitters, PLCs, DCS systems, and multichannel recorders. Connect directly to thermocouple inputs to verify instrument outputs, readings, and display accuracy with confidence.
Measure Thermocouple Sensors with Confidence
Use the PIECAL 322 to troubleshoot thermocouple sensors, identify broken wires, and detect corroded connections. Simply connect the thermocouple and measure the probe directly in degrees Celsius or Fahrenheit for fast, reliable temperature verification in the field or lab.
Lab Accuracy and Long-Term Stability
Designed for high-accuracy thermocouple calibration, the PIECAL 322 features an internal cold junction thermistor accurate to ±0.1°C and traceable to NIST. The sensor is thermally bonded to an isothermal mass with brass blocks and screw terminals for bare thermocouple wire connections, plus a miniature thermocouple connector for quick setup. An extremely stable voltage reference and low-drift components help deliver better accuracy and stability than many handheld and benchtop thermocouple calibrators.
