Adhesive-Back Thermocouple Probes for Surfaces
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.

Adhesive-Back RTD Probes for Surfaces
About the thickness of a dime, these RTD probes stick to surfaces in tight spaces to measure temperature.
Probes that meet DIN EN 60751 adhere to industry standards for accuracy. Probes that meet MIL-STD-108 are submersible, so they can monitor the temperature of water in tanks or containers.

Signal-Averaging Adhesive-Back RTD Probes for Surfaces
 Style B Shown Mounted |  A |
 B |
Measure the temperature of cylinders, pipes, and flat surfaces without installing an immersion probe and where a point sensor may be inaccurate. These RTD probes take multiple temperatures along the length of the probe and average them together for accuracy. About the thickness of a dime, they stick to surfaces in tight spaces.
Probes with a braided stainless steel armored cable protect their wiring from wear and corrosion better than probes with a silicone rubber cable.
Probes that meet DIN EN 60751 adhere to industry standards for accuracy.
