LS225 coating thickness meter with N2000 probe, professional for measuring the coating thickness with large flat area. The instrument uses the eddy current induction principle, the probe uses its own weight to ensure that the same force is used to press the probe during each measurement, and the value is stable. It is especially suitable for measuring the thickness of paint on PCB boards, and can also be used for measuring non-conductive coatings such as paint, anodic oxide layer, ceramics, etc. on non-magnetic metal substrates such as copper, aluminum, die-cast zinc, brass, etc.


LS225+N2000 coating thickness gauge can be non-destructive measurement of non-conductive coating thickness on non-magnetic metal substrates, such as anodic oxide layer on the surface of various aluminum workpieces, three-proof paint on the surface of PCB boards, etc.. It can be used for production inspection, construction acceptance and sales exhibition site, and the application areas involve aviation industry, building materials, machinery, chemical industry, light industry and instrumentation and many other industries.

How to choose the measurement mode of LS225 coating thickness gauge?


  1. 1. The difference between LS225 and other coating thickness gauges

    Compared with several other coating thickness gauges, LS225 has higher measurement accuracy and data repeatability. With a special test fixture, it can be used to accurately measure ultra-thin coatings below 10μm, small size and special-shaped workpieces. It supports zero adjustment and multi-point calibration. The measurement results can be more accurate after calibration through standard films or uncoated workpieces.
