The most basic design consists of a lens to focus the infrared (IR) energy on to a detector, which converts 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. This Infrared IR Thermometer is LCD display, that is the true temperature.                                    Features             Non-contact accurate temperature measuring<br>
 Built-in laser aiming<br>
 ℃/ °F optional<br>
 Low battery indication<br>
 LCD readout, backlight<br>
 Auto-data hold and auto-power off <br>
 Button design, easy to use<br>
 By measuring infrared radiation the thermometer can tell you the temperature of any surface with the touch of a button<br>
 Lightweight and portable, it’s useful for lots of do-it-yourself projects<br>
 Suitable for predictive and preventative industrial maintenance, such as check transformer, connectors, switch devices, rotating equipment, stove and so on<br>
