Simply peel off the adhesive backing on these probes and press them onto a surface to measure its temperature. Without bulky mounting hardware, the thin sensor can slide into crammed spots. You can connect them to controllers, thermometers, and other temperature reading devices to view and store measurements. Pick the thermocouple type that best covers the temperature range you expect your surface to be. 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.

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