The TN1 is a non-contact infrared thermometer,
simply aim the thermometer at the target and press the measurement button to display the surface temperature.
The TN1 indicates temperature over the range of -33 to +220°C with a resolution of 0.1°C.

The distance to target ratio is 1:1 therefore the thermometer should be positioned as close to the target as possible.
The TN1 incorporates maximum and minimum temperature functions together with a lock function for continuous temperature measurement.
The default emissivity is 0.95 but can be changed from 0.01 to 1 if required.
