TN1 infrared thermometer from ETI Ltd.

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 instantly. The TN1 indicates temperature over the range of -33 to 220°C with a resolution of 0.1°C and is switchable between °C/°F.

Each unit incorporates maximum and minimum temperature functions together with an auto power off facility that automatically turns the instrument off after 15 seconds, maximising battery life and a lock function for continuous temperature measurement.

The distance to target ratio is 1:1 therefore the thermometer should be positioned as close to the target as possible. The default emissivity is 0.95 but can be changed from 0.01 to 1.
