The PIE 422 / 422Plus thermocouple calibrator measures and calibrates thermocouple instruments and sensors, including types J, K, T, E, R, S, B, N, G, C, D, L (J-DIN), U (T-DIN) and P (Platinel II). It is available as s single channel RTD (PIE 422) or double channel milliamp and RTD calibrator (PIE 422Plus).

Any temperature value can be set within 0.1° with an adjustable digital potentiometer, and any three temperatures can be stored for instant recall. The PIE 422 / 422Plus thermocouple calibrator can also verify cold junction temperature and output with secondary displays of compensated millivolt setting and cold junction temperature.

The PIE 422 / 422Plus features fast calibration with automatic output stepping. Choose between 2,3, 5, 11 and 21 steps to automatically increment the output in 100, 50, 25, 10 or 5% of span. The step time can be set to match your system from 5, 6, 7, 8, 10, 15, 20, 25, 30, and 60 seconds.
