The 80PR 60 probe expands the utility of your RTD non-contact infrared thermometer by allowing you to take contact temperature readings. You can make contact and non-contact readings at the same time because your RTD infrared thermometer displays the results of both. Just plug the temperature probe into the RTD jack, position the probe tip at or below the surface of your target, and start reading temperatures. (Refer to thermometer user manual for details.)
