The TN2 is a non-contact infrared thermometer, possibly the smallest infrared thermometer with laser alignment on the market today, measuring only 18 x 50 x 100mm and weighing just 62 grams. Simply aim the thermometer at the target and press the read button to display the surface temperature. The TN2 indicates temperature over the range of -33°C to +220°C with a resolution of 0.1°C.

The TN2 thermometer incorporates an optical lens that measures temperature by sensing the amount of radiated energy at infrared frequencies. Using this data and the actual temperature of the infrared sensor (thermopile), the TN2 can calculate the temperature of the surface that emitted the energy.

The distance to target ratio is 3:1 therefore the thermometer should be positioned as close to the target as practical. The TN2 infrared thermometer incorporates maximum, minimum and lock (continuous) functions and is switchable between °C and °F. The unit is supplied with a default emissivity of 0.95, however, the emissivity can be changed from 0.01 to 1.
