LS226 High Precision Coating Thickness Gauge
Applicable to flat plate coating thickness measurement
Gravity-based measurement, stable positioning
Dual screen design, easy reading
1-5 point calibration, suitable for complex applications
The 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 gauge automatically identifies the substrate and switch measurement mode. It is widely used in manufacturing, metal processing, chemical industry, commodity inspection and other fields.
