Good thickness gauge. Relatively precisely works by iron. Breaks the putty to 1900 Micron. There were some difficulties with calibration on aluminum-on the plate originally showed 40 microns and when calibrated changed to 50. He was able to fix it with an iron-20 micron was shown on it and calibrated at 0. After that, he continued the calibration of regular plates. There were problems with IML delivery-they misread the address (the seller indicated it correctly) and the parcel rolled several times at the opposite end of the Moscow region.

The seller quickly sent the goods. He himself wrote the cost of 10s, although I forgot to ask it, well done :) the goods came to Minsk for 3 weeks, was tracked all the way. In the kit case, 2 plates (iron and aluminum) + calibration plastic plates, there is an understandable instruction for Russian. It is powered by a "crown" battery, bought separately. Worst poor calibrated, shows with an accuracy of 0,1...15 units, for finding putty is quite suitable. Defines iron and aluminum. Looks quality. I recommend both the goods and the seller.

I bought a thickness gauge to measure the thickness of plastic bags. With this task, he does not do very well. The testimony floats +/- 5 microns, which for my task is critical. For example: I measure the package with a thickness of 80 microns, and the device shows any values from 75 microns to 85 microns. On the iron (Fe) calibrated well, and on the aluminum (NF) in zero never dropped. And 50/100/250/500/1000 calibrated, but it is zero on aluminum is not put.

Everything came in less than a week. The device works, shows less precisely. For its purpose, just super. I did not try how much battery is enough in the frost, but in a warm room 2 days of constant work on the battery did not affect in any way. The only thing, the size is slightly too big, it's uncomfortable to carry in your pocket.

Excellent goods, came relatively quickly. Everything came unharmed, in the package there is everything as in the description. Calibration performed as written in the instruction, everything works properly. I checked on the car, everything shows. To the seller Thank you very much!
