For the amateur home applications it is quite well suited.
It shows the surface temperature of basically everything.
Be it wall / floor / ceiling and the temp. Of the hob !!
Similarly, I was able to determine the exact opening point of deffekten thermostat from a car.
From the operation and functionally as good to very good.
However, a major problem is temperature variation in the atmosphere!
Lag the device for example in a space where it is below 15 ° C, it shows incorrect values!
About 15 ° C it shows but at reliable.
The inaccuracy is 20 ° C at 2-5 ° C.
Nevertheless, if you know this weakness, one can very well work with it.
