1.2" LCD Non Contact Digital InfraRed Thermometer with Laser Sight (-50°C ~ 380°C)

In is not acurate.
In temperatures in range 0-10C I see difference from real temperature like -+4 C. But what is bigger problem. The difference is not stable. I measured something that had to have 9C, it showed 4C and after 10 minutes measuring somewhere I returned and measured same thing and it showed 7C. Next day I measured room with temperature 7C and some objects had 2C some -0,5C.
It has internal temperature sensor, that is correct, there must be something that measure temperature of sensor, but together it do not work right, because when I measure in room temperature 23C parts of furniture that have also 23C it shows something in distance +-1C, then I cooled this device to aprox. 10C and the same object in the room was like 26C, it is +3C.
