Coating Thickness Gauge


The Coating Thickness Gauge can non-destructively measure the thickness of non-conductive coatings on metal surfaces, as well as non-ferromagnetic metal coatings on ferromagnetic metals (e.g. Iron, Nickel or Cobalt). Specific applications include measuring iron, stainless steel surface paint or galvanizing layer thickness.

The Coating Thickness Gauge has a built-in magnetic induction and eddy current effect probe, with a measurement range of 0 to 2000μm and a measurement accuracy of ±(2% + 1μm).

During the process of shrinking the probe to the inside of the instrument, the instrument can automatically distinguish the properties of the substrate and measure the thickness of the coating (plating) layer. The measurement results can also be sent to the mobile application in real time by bluetooth.

The instrument has two displays, the large OLED screen is on the front of the instrument and the smaller OLED screen is on the top of the instrument. The dual-screen display allows users to view the measurement results from different angles. The OLED display screen is used to enhance the low temperature performance.

The product is suitable for car paint inspection: while measuring paint thickness, it can also identify iron galvanized and iron powder putty materials. The instrument has strong anti-interference ability and can work normally in a more complex electromagnetic field environment.
