The device is equipped with a laser sight that allows precise targeting of the test point. The device uses good quality materials, and the ergonomic design improves the comfort of using the thermometer. The backlit display allows you to work with your device in the dark. The pyrometer is equipped with an automatic shutdown function increasing savings in battery consumption. The pyrometer has an emissivity regulation. Emissivity is the ability of a material to reflect an infrared signal emitted by a pyrometer. This allows you to measure more precisely. The pyrometer is not a medical device, it is not designed to measure body temperature.
