Mr Goh Lin Hong, director of an electroplating company that specialized in chrome coating has got a really bad experience from a low cost China made coating thickness gauge. He made the purchase for two units of the low cost China coating thickness gauge sometimes ago and it only lasted for a few times of measurement!
 
We recommended him a world leader in coating thickness gauge, Elektrophysik from Germany and, as China does have good reliable manufacturer,  TIME, a company established more than 25+ years . The measurement proofed accurate for titanium coating thickness of around 8 microns on tool steel in our office a moment ago.
