Thermocouple Probes with Armored Cable for Solids
To shield the wiring from corrosion and wear in harsh environments, these probes have an armored stainless steel cable. Use their narrow tip to pierce pliable plastic, rubber, and other soft solids to check the internal temperature. They’re also known as penetration probes. Often plugged into hand-held thermometers, they have a handle for a comfortable grip. 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.
These thermocouples are manufactured to conform to ASTM E230 for accuracy. Accuracy is how far off the reported value is from the actual temperature.
Needle-tip probes minimize puncture damage when inserted into sensitive materials and small objects.
Insulated probes have a layer of magnesium oxide inside for extra protection around 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.
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 are filled with magnesium oxide for extra protection around the internal wires.
