Pretty good for the price

As a (amateur) Fahrzeugaufbereiter I use the device to determine the remaining resist thickness on both ferrous and aluminum on. One should know in advance how "sharp" you can polish a vehicle before you see the primer yes :)

The device does its job, the measuring inaccuracy lies with each 1-5μm at an acceptable level, where you have to have removed at 5 .mu.m deviation already far (50 microns) from the calibrated range. "Vorpeilen" One must first of all, with what kind of thickness you it has to do about, and then use the enclosed metal plate and plastic foils (simulating a "layer") "Einnorden" in each area.
And at the point the device loses one of the 5 star rating: The calibration is, for technical reasons, already tricky enough, the imprecise manual (the blue button is not blue, the menu screen is not always exactly as described in the manual). No deductions for this is bearable. The up / down keys, however, with which one calibrated nervous. Although every time comes a confirmatory beep, you have partially press a button until the value to a count up or down is up to 6 times. Therefore, the calibration costs a little nervous - and the product a rating Star.
