RTD probes – or resistance temperature detector probes – are sensors that record temperature through differences in resistance. Various industries rely on these probes for accurate and consistent temperature measurements. However, if left uncalibrated, RTD probes can begin to drift from their original accuracy as they age. Incorrect RTD probe readings can result in compromised product quality, lost time, and added costs. Probes should be periodically calibrated by a professional so that they can continue to deliver valid, reliable results.
