Now we are pleased to introduce this Xintest HT-812 -50℃-450℃ Infrared Thermometer to you. It features a basic design consisted of a lens to focus the infrared (IR) energy on to a detector， which converting the energy to an electrical signal that can be displayed in units of temperature after being compensated for ambient temperature variation. This configuration facilitates temperature measurement from a distance without contact with the object to be measured. With LCD display design， it is easy to read. A useful and practical infrared thermometer you should not miss!
