Transcat offers thermocouple calibrators, RTD calibrators, and instruments for calibrating both T/Cs and RTDs. The thermocouple calibrator measures and simulates specific thermocouple types over an industrial temperature range for testing purposes. Handheld models are available with the capability to measure mA signals while also sourcing a temperature signal. Within our T/C calibrator selection, you can find the ideal instrument to test transmitters, controllers, alarms, indicators, and computer systems. Our reliable RTD calibrators measure and simulate RTDs and resistance. We offer a full line of instruments for checking probes, indicators, recorders, controllers and more.
