LS221 Coating Thickness Gauge

LS221 Coating Thickness Gauge


      Ⅰ.Brief Introduction  

      The LS221 coating thickness gauge can be used not only to measure non-magnetic coatings such as paint, varnish, enamel, chrome and galvanizing on ferromagnetism metal substrates such as steel or iron, but also measure Non-conductive coatings such as paint, anodized layers or ceramic on non-magnetic metal substrates such as copper, aluminum, die cast zinc, brass etc.

       The LS221 coating thickness gauge can automatically identify the substrate and switch measurement mode. External cable probe is more convenient to test narrow space . No calibration, just zero adjustment.

       Standards for the product:
       GB/T 4956-2003 Non-magnetic Coatings on Magnetic Substrates-Measurement of Coating Thickness-Magnetic Method
       GB/T 4957-2003 Non-conductive Coatings on Non-magnetic Basis Metals-Measurement of Coating Thickness-Eddy Current
       DIN EN ISO 2808 Paints and Varnishes-Determination of Film Thickness
       JJG-818-2005 Verification Regulation of Magnetic and Eddy Current Measuring Instrument for Coating Thickness
