Measure air and surface temperatures in corrosive environments—an armored stainless steel cable shields the wiring on these probes from wear, abrasion, and corrosion. The tip of the probe is exposed for rapid response times. Because it’s exposed, these probes are not for use in liquids. They are manufactured to conform to ASTM E230. Accuracy is how far off the reported value is from the actual temperature.

Note: When installing probes with wire leads, the red wire is negative.

Thick wire with ceramic insulation stands up to extreme temperatures in forging, die casting, and heat treating. These probes have an exposed tip that's quick to respond to air and surface temperature changes but can't be used in liquids. Pick the thermocouple type that best covers the temperature range you expect the air or surface 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.

Plug these probes into a handheld thermometer to check air temperature on the go. They have a handle for a comfortable grip and a coiled cable that stretches when you need extra reach. With an exposed sensor tip, these probes are quick to respond to air temperature changes but can’t be used in liquids. Perforated stainless steel shields the sensor tip, protecting it if it’s hit or bumped as you measure.

These thermocouples are manufactured to conform to ASTM E230 for accuracy. Accuracy is how far off the reported value is from the actual temperature.

With a clip on the end, these probes are quick to install and easy to remove. They're often used on vents, circuit boards, and other irregular surfaces. Their tip is exposed, so they respond to rapid changes in air temperature but can’t be used in liquids. The coiled cable stretches when you need extra reach.
