Main Features

Non-contact infrared thermometer IR-819 accuracy can be ensured while the temperature is at 18℃ to 28℃. If the ambient temperature of the thermometer changes greatly, the accuracy of the thermometer will be affected. wait for 30 minutes at the new ambient temperature before measuring. Ensure that the size of the target is larger than the spot size of the unit. If the target is small, the distance to it should be reduced. In situations where precision is essential, ensure that the target is at least twice as large as the spot size.


Non-contact infrared thermometers measure the emissivity of a material’s surface, which indicates how efficiently it emits energy as thermal radiation. It is calculated as the ratio of the thermal radiation from the material’s surface to that of an ideal black surface at the same temperature. the ratio varies from 0 to 1. A higher emissivity value indicates stronger thermal radiation from the surface. most materials have emissivity values between 0.85 and 0.98. the default emissivity of this unit is 0.95 and can be adjusted. before measuring, please refer to the table below to set the emissivity to the appropriate value.
