PIE'S 322-1 is designed for easy use. With the 322-1 you can check and calibrate all your thermocouple instruments and measure thermocouple sensors. You can take it to the shop, plant or field. Carry it without worry as it comes protected with a rubber boot and rugged low profile switches. Easy to operate even in dark areas of the plant with the backlit display.
Calibrate directly in temperature, C/F. You now can stop carrying around a millivolt source and thermocouple tables. The 322-1 works with the 4 most common thermocouples (J/K/T/E). Easily set any value quickly to within 0.1C with the adjustable digital potentiometer "DIAL" plus store any 3 temperatures for instant recall with the EZ-CHECK switch. Or calibrate from -13.000 to + 80.000mV.
Fast calibration with automatic output stepping. You can choose between 2, 3, 5, 11 steps and ramp to automatically increment the outputs in 100%, 50%, 25%, 10% or 5% of span. Select the step time to match your system from 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 60 seconds.
Comparable with all process instruments. No competitors calibrator is compatible with as many process instruments as PIE'S 322-1. Connect directly to the thermocouple inputs of transmitters, PLCs, DCS & multichannel recorders to verify their outputs or displays.
Measure thermocouple sensors. Trouble shoot sensor connections and find broken wires or corroded connections. Connect your thermocouple and the 322-1 measures the probe in degrees C/F.
Calibration lab accurate and stable. The internal cold junctions thermistor is accurate to +/-0.1C and is traceable to NIST. The sensor is thermally bonded to an isothermal mass which includes brass blocks with screw terminals for connection of bare thermocouple wires along with a mini thermocouple connection for fast connections. The circuitry uses an extremely stable voltage reference and low drift components which makes the 322-1 more accurate than most other handheld and benchtop thermocouple calibrators.
