I just received my IR thermometer, and I started to play with it.
The quality of the product feels astonishingly good for a so cheap product. The touch of the plastic and the grip are nice. Usage is very simple: just aim and pull the trigger. Other buttons allow you to switch between Fahrenheit and Celsius, to turn off the laser and to backlight the screen.
Now I need time to measure my various power supply, using a minimal protocol. Meanwhile, this tool is awesome, I spent a good time to measure the world around me: light bulb, coffee, fridge and freezer, wine ...
For example, this pot of ice!
And when everything was measured, thanks to its laser pointer, and its pistol grip (and a little imagination) can still exploring uncharted worlds armed of this phaser.
