HIGH ACCURACYCombining the latest temperature sensor technology and an advanced Fresnel lens, this instrument reads high accuracy values down to 2% in just 0.5s; The adjustable emissivity is 0.1 to 1.0, which can measure the surface temperature of different objects more accurately. PRECISE POSITIONINGBuilt-in red laser for precision aiming, accurately finding the measuring target; Large color screen, clear reading. The distance to spot ratio is 12:1, which means you can measure the target at a longer distance. MORE APPLICABLE FUNCTIONSThis infrared thermometer accurately tests temperature during -581112 (-50600); Switch between Celsius/Fahrenheit measurements as needed; has an LCD backlight so you can see temperatures even in the dark; Auto power off feature helps you save battery power.
