Industrial Temperature Calibration Equipment

Temperature measurement is the most critical and widely measured parameter in many industrial processes. Proper verification of your temperature sensors is crucial for
maintaining product quality, energy efficiency and workplace safety.
Temperature calibration involves comparing your temperature sensor, typically a platinum resistance thermometer (PRT, RTD, PT-100), thermistor, or thermocouple to a traceable temperature measurement system in a stable thermal source.
Isotech manufactures the widest selection of dry-block calibrators, portable calibration baths, digital readouts, sensors and infrared calibrators to keep your industrial processes running smoothly.
