The processing is usual good as its predecessor. The plastic acts with value and the surface of rough plastic grip. By means of the 3 keys on the front panel, you can:
switch the temperature unit in Celsius or Fahrenheit
the laser beam for sighting on or off
The blue display light on or off
The laser thermometer basically measures all temperatures between - 50 to + 550 ° C. Note, however, that the measuring surface is but the greater the farther the object to be measured is removed. Therefore, it is the exact measure important to be as close to the DUT off.
The longer you have at home, laser thermometer, the more areas of application can be found. So I've already checked the temperature of food in the refrigerator (at different heights), heat dissipation of electrical appliances and heating systems.
Measurement accuracy, I guess this one as well. Incidentally: The power is supplied by a 9V battery which was there already in delivery. I recommend to leave it off the blue lights for the economical operation, the display is rich in contrast and easy to read during the day.
Price / quality I find very fair. Due to the use of the predecessor we know that with this unit, even with frequent use so far no problems have occurred.
