Ensuring process temperature accuracy involves calibrating not only the system’s electronic temperature signals, but also the very temperature sensors that initiate those signals. Rugged Fluke handheld temperature calibrators source and measure RTDs and thermocouples, power transmitters, and store data. Fluke Calibration temperature sources cover temperatures from -45 °C to 1200 °C and include handheld, portable, and benchtop calibrators. Infrared thermometer calibrators and reference measurement thermometers ensure every necessary tool is available to you. In addition to the process temperature calibrators below, higher-accuracy temperature calibrators are also available.
