Versatile handheld IR meter, temperature range -50...1000°C, adjustable emissivity coefficient, D-t-S ratio 30:1. Infrared thermometer is very useful when establishing differences in temperatures.
If surface materials vary, the IR meter can detect temperature differences even in constant ambient temperature. For this reason, an infrared thermometer cannot be as accurate as an handheld, thermocouple or Pt100 sensor equipped meter, if the emissivity of the materials is not known. The accuracy can be increased by using an adjustable emissivity coefficient in places, where emissivity deviates from value 0.95. In common materials, such as wood, plastic and painted surfaces, emissivity is typically 0.95. Metallic and shiny surfaces deviate significantly from this value, which means that the emissivity coefficient needs to be recalibrated depending on the surface material to be measured. In painted metal surfaces, the emissivity coefficient is 0.95.
The meter is fitted with a double laser sight, which makes the distance-to-spot ratio easy to define. The D-t-S ratio is 30:1, which means that the measurement point diameter is 10 cm at a distance of 3 m, and 5 cm at a distance of 1.5 m.
