Thermocouple Probes for Air and Surfaces
With Wire Leads
Press the tips of these probes against a surface to measure its temperature or leave them untouched to measure air temperature. The tip is exposed for rapid response times. Because it’s exposed, these probes are not for use in liquids.
Note: When installing probes with wire leads, the red wire is negative.
