Fluke 568 Ex provides infrared and contact temperature measurements in hazardous industrial areas. The IR channel covers −40 to +800 °C, and a 50:1 distance-to-spot ratio supports smaller targets at greater distances. The type-K input enables contact checks; the included probe has a different range from the instrument input. Set emissivity from the material table or digitally from 0.10 to 1.00. The instrument stores 99 points and provides high/low alarms and Min/Max/Avg/Dif functions. Determine the permitted Ex area, batteries, probes and connections from the safety documents for the selected version. A type-K probe and conductive protective case are included.
