Product Review

ZOTO infrared thermometer is suitable for non-contact temperature measurement. The thermometer determines the surface temperature of the object by measuring the infrared energy of the radiation from the surface of the object.
It is very convenient to use this laser infrared thermometer, just point the object you want to measure,  press the measurement trigger, and you will know the temperature instantly.
Versatile use, can use the thermometer gun on moving engine parts, automobile maintenance, barbecue grills, cooking, swimming pools, ovens, air ducts, electrical engineering and that are not convenient to get touch. 
The alarm indicator turns to red when the measured value is beyond or less than setting temperature,and the limit temperature can be set by yourself.

Notes
Laser is used only for aim and is independent of temperature measurement, which can be turned on and off independently.
Replace the batteries when indication of battery power is insufficient, so as to prevent measurement error.
Do not use products in the environment of explosive gas, water vapor or dust.
For actual temperature, please refer to the emissivity information. Reflective objects will cause the measured temperature to be lower than the actual temperature.
Do not use a solvent to clean the thermometer.
