The PIE 820 / 820PM multifunction process calibrator combines all milliamp loop functions, sources and reads DC Volts and millivolts, 14 thermocouple types, RTD curves, ohms, and process frequency signals.

The PIE 820 / 820PM multifunction process calibrator sources and reads types J, K, T, E, R, S, B, N, G, C, D, L (J DIN), U (T DIN) and P (Platinel II) thermocouples. It also sources and reads Pt 100 Ohm (3850, 3902, 3916, 3926) & 1000 Ohm (3850) Copper 10 & 50 Ohm, Nickel 100 and 120 Ohm RTDs.

All ranges have auto storing MIN/MAX readings and three output set points for fast calibration of zero, midpoint, and span. Advanced features include automatic detection of 2, 3, and 4 wire RTDs plus configurable automatic stepping and ramping.

The PIE 820PM is the panel mount version of the PIE 820, and includes 8.75in x 4.75in aluminum mounting plate, screws, and an 110/120V AC adapter.
