Take temperature readings in high-vibration environments. These probes bolt onto motors, machines, and other equipment, so they won’t shake loose. 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 device you plan to connect it to. They’re often used with temperature controllers, thermometers, and other temperature-reading devices.

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

Probes with wire leads offer more flexibility than probes with connectors already attached because you can either wire them to a terminal block or add your own connector. For installation, note that the red wire is negative.
