The Fluke 80T-IR/E Extended Range Infrared Temperature Probe (the probe) is a noncontact temperature measurement accessory for use with a test instrument capable of measuring DC volts in the millivolt range such as a digital multimeter (DMM). The probe has a temperature range of 32°F to 1000°F, with a basic accuracy of 3% of reading, and an output of 1 mV dc per °F. Temperature is measured by pointing the probe at the surface to be measured, and reading the temperature on the test instrument display.
