Overview
The PIE 422Plus is a 2-in-1 diagnostic milliamp and laboratory thermocouple calibrator. The milliamp side sources and reads 0.000 to 24.000 mA, simulates two-wire transmitters, powers and measures with an internal 24 V supply, includes a 250 Ω HART resistor, and offers patented Ground Leak Detection.
Thermocouple accuracy is ±(0.008% of reading + 0.006 mV) with ±0.05 °C cold-junction compensation. Source and read types J, K, T, E, R, S, B, N, G, C, D, L (J-DIN), U (T-DIN), P (Platinel II), and −13.000 to 80.000 mV. When certified by an accredited laboratory, it is capable of meeting AMS 2750 Field Test Instrument requirements.
Palm-sized with rubber boot and backlit display; automatic stepping from 2 to 21 steps. Made in the USA with NIST-traceable calibration.
