The operation is very simple because just point the place which we want to know the temperature.
A bit is expected that the temperature stabilizes (1 to 5 seconds).
It therefore takes the risk not to burn or an electric shock.
In practice, we realize that the uses are numerous:
- Temperature rise of electronic components
- Cooking thermometer (caramel)
- Verification of the thermal insulation (eg a house)
- Temperature in a refrigerator, freezer, oven, ...
- Heating of machine parts
- Up / down temperature of some mechanical and electronic elements.
- ...
The precision of the device seems to me very correct, especially for my use.
The handling and use are immediate, if only one has a 9V battery at home.
