Sanitary Thermocouple Probes for Liquids and Gases

Designed to measure temperature in dairy and food-processing applications, these probes are built to maintain sanitary standards. They have a sanitary quick-clamp connection that’s easy to disconnect for cleaning. IP65 and NEMA 4 rated, they seal out water from washdowns from top to bottom. The probes are polished stainless steel, so they're easy to clean and won't corrode from harsh cleaning chemicals or immersion in liquids or gases. The stainless steel also shields the sensor inside from impact, while magnesium oxide protects the wiring. Remove the cap on the head to wire the thermocouple to your application. The fitting is welded on, so you can’t adjust the probe’s length.
Pick the thermocouple type that best covers the temperature range you expect your liquid or gas to be. You should also make sure the thermocouple type you choose is compatible with the device you plan to connect it to. They’re often used with temperature controllers, thermometers, and other temperature-reading devices.
These thermocouples are manufactured to conform to ASTM E230 for accuracy. Accuracy is how far off the reported value is from the actual temperature.
