Description
NOTE: NOT for human. Helect infrared thermometer can be used both daily and industrial temperature measurement, such as cooking, refrigeration, steel, glass, plastics, food and so on
°C/°F switchable, automatic data hold, backlit LCD, low battery indicator, auto power off function. 9V Battery is included
Easily and quickly measure temperatures from a safe and hazard-free distance. NOTE: The diameter of the object under test must be bigger than the laser spot size
Built-in red laser for precisely aiming. Distance Spot Ratio: 12:1, great to measure a long distance target
Measurement range: -50°C to 550°C/ -58°F to 1022°F; Portable and anti-slip design makes it easy to get the temperature outdoors and indoors

The device is easy to use: simply hold trigger to get continuous readings (scan) with 1/2second lag – so scan slowly. Release the button and it will hold the last reading – useful when taking a reading and are unable to see the display. The display has a on/off backlight to assist if needed.
I have tested this on various known temperatures (fridge freezer icy water boiling water) and readings are reasonably accurate.
Beware: on my device the laser-spot is way off the alignment of the gun (a good 12cm out at 3meter distance) so be cautious if taking measurements at a distance. Also be aware that the ‘cone’ of the IR detector has field of view of 12:1 so at 3 meters distance it will show the temperature for a 250cm diameter area. So to get an accurate reading for a small area you need to be close to it.
Finally: different materials/surfaces have different IR Emissivity Values in that a matt-black surface will display a higher IR reading than a white or reflective one. The instruction leaflet provides an Emissivity Value table for various materials but it fails to explain how to use them. I am of the understanding that you DIVIDE the displayed reading by the Emissivity value (always less than 1) so that the actual/calculated temperature will be higher than that displayed.
I’d happy give 5 stars if the guidance laser was more accurately aligned to the physical hand-gun although the separate IR detector could also be misaligned. And slightly better instructions.

Product arrived in time. Sturdy casing and I use it in a supermarket to check freezers and chillers and it works perfectly. Very pleased with it

it was my mistake that i didn”t read carefully where it states it”s not for human temperature measurement although in specs it says accuracy is +-3 degrees on skin it”s more like 5-7 degrees …
