Industrial Temperature Calibrator Selection Guide
| A temperature calibrator, often called a thermometer calibrator, is used to remove inaccuracies in installed thermometers and temperature sensors, because temperature measurement is a critical parameter in many industrial processes. Although simulators are sometimes called temperature calibrators or thermometer calibrators and may be used to provide calibration for the electronics in an installed system, a temperature source with a calibrated reference sensor is still required to provide a complete and meaningful calibration. Fluke Calibration offers a complete selection of dry-block calibrators, Micro-Baths, and infrared calibrators (i.e. blackbody calibrators) for temperature calibration at the accuracies required by today’s industrial processes.
