Calibrate process thermocouple instrumentation with a PIE Thermocouple Calibrator

Thermocouple Calibrator

PIE has a thermocouple calibrator to fit your needs from the PIE 520B single type thermocouple simulator  to the advanced troubleshooting capabilities of the PIE 422Plus. Have you had issues in the past where your thermocouple calibrator wouldn’t work with some of the instruments in your plant? Our thermocouple calibrators are guaranteed to be compatible with all process thermocouple inputs including all brands of smart temperature transmitters, PLC input cards, DCS systems and multichannel recorders.

PIE thermocouple calibrators have fuse-less protection, rugged design, and long battery life. The PIE 422, 422Plus and 525B display in °F and °C along with the millivolt value from the temperature vs. millivolt thermocouple tables. The PIE 322-1, 422 & 525B have sockets for fast connections using miniature thermocouple plugs as well as brass blocks and screws for attachment of stripped thermocouple wires. The brass blocks also add stability to the NIST traceable cold junction reference, a high precision thermistor (±0.05 °C) rated for 11 years!

The PIE 422Plus adds a FULL function milliamp calibrator plus it reads and sources 14 thermocouple types. It also includes PIE’s patented Leak Detection to find hidden problems in 4 to 20 milliamps loops.

The PIE 525B sources and measures 12 RTD types along with 14 thermocouple types. Additional features on the PIE 525B include high resolution to 0.01°, automatic detection of 2, 3 and 4 wire RTDs, and can display the excitation current used by the RTD instrument to measure an RTD sensor.

Need to replace an Altek Thermocouple Calibrator?

Altek was the world leader in thermocouple calibrators but has discontinued manufacturing all products. PIE thermocouple calibrators, designed by the same engineer as the Altek models,  are the ideal replacement!  With even smaller size, similar functions, updated designs and improved accuracy and repeatability.  To find the best match for your discontinued Altek Calibrator click  here:  Replace your Altek Calibrator
