As a new buyer in the Industrial and Scientific market I was impressed by this product's ability to accurately measure the thickness of coatings on various surfaces. As a result of my tests, I determined that it provides reliable measurements with consistent results... The portability of this device is also a great benefit, as it easily fits into my tool kit for on-the-go jobs. The only con is that it is slightly pricey compared to other similar products on the market. Overall, a great investment for any professional looking for precise coating thickness measurements..
