Precision Sensors & PRT Probes


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.


Application-Specific PRT Probes


Consider how a probe or sensor fits your needs in terms of: application, operating environment, measurement range, accuracy, stability, dimensions and construction. Platinum is the metal of choice for precision measurement, leading to the widespread use of the platinum resistance thermometer (PRT). Whether you’re looking for a precise PRT probe or another type of instrument, make sure the product meets your media and contact surface requirements. Will you be immersing the probe? Can it withstand low temperatures? Should it be explosion proof? Also, remember, a probe may be built to work with a specific brand of readout device.


Rugged Temperature Measurement Tools


Fluke precision industrial PRTs read temperatures up to 420 °C, with ± 0.025 °C accuracy, and offer shockproof designs in three lengths. Fluke freezer probes are RTDs that measure accurately in temperatures as low as –100 °C. They’re ideal for confirming autoclave performance. Dwyer Instruments’ air temperature sensors offer improved accuracy by minimizing the effects of radiated heat.


Buy Calibrated Precision Sensors Only from Transcat


Because Transcat operates dozens of ISO 17025 Accredited Calibration Labs across the United States and Canada, we are uniquely positioned to offer new instrument calibration services on most of the items we distribute.  If your quality system requires that your instruments have a valid calibration certificate at all times, take advantage of our precision sensor calibration capabilities so that your instrument arrives ready to be put into use.
