Many a classic car owner wants to be sure of the review of the cooling system of his expensive motor that nothing is too warm. Or whether the supposedly from outside yet nice looking cooler is actually not yet plugged into parts and not really doing his service. One can easily see with such a useful particles now. Quick draufgehalten the laser thermometer and already you can see the temperature (and hopefully satisfied with the result). It was me definitely on my line engine, the thermal state had a healthy despite high outdoor temperatures. And it stays clean ... Since then, I always in the trunk had such an affordable particles (and many other vintage lovers also can soothe). Of course, limits the applications are hardly set. Also works with disc brakes (smoothly?), Tire tread (track set correctly?), Fuse boxes, cable connections, etc., etc.
