Descriptions :
GM550 Non-Contact Digital IR Laser Infrared Temperature Meter Gun Thermometer Tester -50-550¿¿¿
Lightweight and compact. Simple One-Handed operation. Celsius and Fahrenheit switchable.
TR sight allows accurate targeting.
Laser sight allows accurate targeting.
Simply point to an object and read its temperature.
Precise non-contact IR thermometer, safe and easy to use. 
Laser on/ off switch, 7 seconds auto power off & temperature data hold.
Consist of optics, temperature sensor, signal amplifier, processing circuit and LCD display with backlight.
The optics collected the infrared energy emitted by object and focus onto the sensor. Then the sensor translates the energy into an electricity signal. This signal will be turned out to be digital shown on the LCD after the signal amplifier and processing circuit.
Suitable for :
hot water pipes, hot engine parts, cooking surfaces, hot tubes insulation, electrical connection, ballasts in electric lights, electric motors, bearings, wine coolers hot asphalt, swimming pools, fish tanks, hot & cold food products, heating air conditioning, etc.
NOTE :
1.The distance to spot size of the unit is 12 : 1.
2.Do not point laser directly at eye or indirectly off reflective surfaces.
3.Do not use this unit in the environment of explosive gas, steam or dusty.
4.Most organic materials and painted or oxidized surfaces have an emissivity of 0.95(pre-set in the unit).
5.Measure the tape or painted surface when the tape or painted reach the same temperature as the material underneath.
6.Inaccurate readings will result from measuring shiny or polished metal surface. To compensate, cover the target surface with masking tape or flat black paint.
