The LS221 Coating Thickness Gauge is a specialist instrument for measuring the thickness of coatings on metal surfaces. The instrument combines the Hall effect and Eddy current principles to measure the thickness of non-ferromagnetic coatings on ferromagnetic metal substrates and the thickness of non-conductive coatings on non-magnetic metal substrates. The host and probe of LS221 is separate, which makes it easy for the user to view the data under complex testing conditions. It can be used in the laboratory and engineering field. 

  • 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. 

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

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

FAQ

  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.
