Hand-Held Thermocouple Probes for Surfaces




Often used with thermocouple thermometers, these probes have a handle for a comfortable grip. The cable coils neatly to avoid tangles as you move but is easy to stretch out when you need extra reach.
These thermocouples are manufactured to conform to ASTM E230 for accuracy. Accuracy is how far off the reported value is from the actual temperature.

Hand-Held Magnetic Thermocouple Probes for Surfaces


Measure temperatures around your facility by sticking these probes onto magnetic surfaces. They come attached to a cable that's ready to plug into a handheld thermometer. The handle provides a comfortable grip as you move from spot to spot. It also keeps your hands at a safe distance from hot surfaces as you use the probe. Thanks to their high-strength magnet, they'll stay firmly in place even in high-vibration spots, like on motors and bearings. For accurate readings, a spring pushes the probe tip forward, keeping the tip in constant contact with the surface you're measuring.
Pick the thermocouple type that best covers the temperature range you expect your surface to be. You should also make sure the thermocouple type you choose is compatible with the devices you plan to connect it to.
These thermocouples are manufactured to conform to ASTM E230 for accuracy. Accuracy is how far off the reported value is from the actual temperature.

Hand-Held Thermocouple Probes for Air


Plug these probes into a hand-held 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.
Insulated probes have a layer of magnesium oxide inside to protect the wiring.

Thermocouple Probes for Solids


Pierce pliable plastics, rubber, and other soft solids to check the internal temperature. Also known as penetration probes, these thermocouple probes have a stainless-steel housing with a narrow tip. They are often plugged into hand-held thermometers and have a handle for a comfortable grip. A coiled cable helps avoid tangles for neat and compact storage, while also allowing you to stretch it out when you need more reach. Pick the thermocouple type that best covers the temperature range you expect your solid to be. You should also make sure the thermocouple type you choose is compatible with the device you plan to connect it to.
