LS220H is an integrated high-precision coating thickness gauge, which combines the Hall effect and eddy current thickness measurement principles. This gauge can be used for coating thickness on various metal substrates.

  • There are only four types of ferromagnetic metal elements at room temperature: iron, cobalt, nickel, and gadolinium.

  • Common non-ferromagnetic metals: copper, aluminum, magnesium, zinc, chromium, etc.

  • Hall effect: can be used for the measurement of non-ferromagnetic coatings on ferromagnetic metal substrates.

  • Eddy current: can be used for the measurement of non-conductive coatings on non-magnetic metal substrates.

  1. 1. The difference between LS220H and LS221

    The functions and parameters of LS220H and LS221 are exactly the same, but the LS220H coating thickness gauge adopts an integrated design and can be operated with one hand; while the LS221 adopts a split design, the probe size is smaller, which is suitable for measuring narrow spaces and some special positions.
