Never thought for this price to get as good a working laser thermometer.
The required 9-volt battery and a short English manual included.
The quality of workmanship and the material to make a great impression in my case. Nothing cracks and creaks. The material seems slightly rubberized so the handling is very stable and not slippery free. The onset of the 9 volt block is somewhat tricky because care must be taken, the cable not to solve some of the inner board. The total weight of what I call easy.
It is important to equipment and above all the measuring accuracy.
The measuring range is targeted either with or without laser spot. The device switches off after pressing the measuring button front immediately so that the measured temperature value is displayed. A holding it pressed the measuring button for about one second initiates the scan and the current adjusted temperature can be monitored directly on the display. After releasing the button, the value is stored and. Optionally, additionally activates the backlight and the laser beam for better targeting information of measurement points. The button itself has a reliable tactile feedback.
The repeatability is very high at an identical site. The approach used for the measurement measurement point increases conically with increasing distance from the device to the object from 300mm to max. 1500mm.
Yet this question of repeatability hot liquids hardly represents when these break down steadily temperature.
To times quickly measure temperatures from freezer, refrigerator, oven or hot liquids etc. absolutely convenient as measuring only contactless come partly in question.
I hope I could give you a little help for your buying decision. I would again buy these thermometers at any time.
