Features 1、Smart Testing: The coating thickness gauge can record the average value, maximum value, minimum value, and quantity value at the same time. The measurement range of 0‑2000um and high accuracy ensure easier working. With automatic shutdown function to save battery power. 2、Clear Display: Paint depth gauge with large display will clearly show the metal type, operating mode, data, battery status and reading in µm or mils. 3、Wider Utility: Used to measure the thickness of coatings and inks, widely used in manufacturing, metal processing industry, chemical industry, commodity inspection and other fields. 4、Better Design: The high definition display screen of the paint meter has a background light, making it much easier to read the data. The non slip design is comfortable to hold, which can be placed anywhere and is easy to carry. 5、Reliable Work: Able to inspect the paint thickness as well as detecting the concealed dent and blemish, very practical and reliable.
