For Model with thermocouple socket

The non-contact infrared thermometer is the ultimate tool for temperature measurements. It can measure from 100 to 1800 oC (212~3272 oF) in the
distance of 75:1 DS (Distance to Spot) ratio. Furthermore, the memory mode can record and display the specific measurement with emissivity. There are
many mathematical modes for the Infrared function.
* Please remember to keep away from children and don’t use it for safety related applications.

Simply aim the thermometer at the measure target with Lens (○11) and press Meas. key (○8) to display the surface temperature. The

Distance:Spot is 75:1. The two laser points are the reference for the target spot size. Please make sure the target area is within the field of view.
