Probes And Sensors

We stock RTD, PRT, thermocouple and thermistor types of sensors and probes that provide highly accurate measurements of liquid, gas, or surface temperatures. Our sensing assemblies and probes with sensing elements are built by leaders in temperature measurement, such as Fluke and Dwyer. When searching for a fast-response sensor, you’ll find our RTDs and thermistors deliver accuracy and repeatability. Reliable thermocouples are also an option for control and monitoring. Transcat products meet the rigorous demands of the manufacturing, process and food service industries. We have probes in a comprehensive range of configurations to support internal, external, or flowing temperature measurement.
