He took the device for use both at home and at work for non-contact measurement of electric heating equipment.
Infrared thermometer measures the surface temperature of the object. The receiver module thermometer is sensitive to the emitted , reflected, and transmitted energy that falls on it and focuses on the sensor . Electronic thermometer module converts information received from the sensor and displays it on the display in units of temperature.

The module laser pointer is used only for guidance on the measurement object . You must ensure that the target is larger spot size measurement instrument.


Below the display are three knopki.Otklyuchenie lighting , turning off the laser and switch C / Farengeyta.Pitaetsya from 9 volt batteries . Included in the kit. The compartment is located in the handle . Leans forward. It weighs 164 grams with the battery .

Optical resolution in the infrared thermometer is 12:1 , which means that at the distance of 1.2 m diameter spot size should be no more than 10cm. The smaller the target , the closer it should be located to the thermometer.
When accuracy is critical , make sure the target is at least twice the diameter of the unit's spot .

For the detection of the heating zone at the first place the thermometer area located outside the surface of interest . Then, moving up and down the thermometer , it gradually shifting toward the object of measurement has not yet determine the location of the hottest zone.

Not recommended measuring shiny or polished reflective metal surfaces ( stainless steel, aluminum) . To avoid inaccurate measurements paste on a surface sticky film or apply black paint stripe.
Infrared thermometer can not measure through transparent surfaces such as glass , since This occurs when the glass surface temperature measurement .

The measurement accuracy depends on the emissivity of the material being measured .
The emissivity (or emissivity ) - shows the ratio of the energy of thermal radiation gray body , according to the Stefan Boltzmann constant, the radiation of a black body at the same temperature . The emissivity of a black body = 1.
The unit is set to the emissivity of 0.95. Accordingly accurately measure the temperature of objects will have this degree of blackness or close .

Perfect priborchik.Mozhno use in various fields, both at home and at work . You can buy.
