Bluetooth Coating Thickness Gauge

Bluetooth Coating Thickness Gauge

Coating Thickness Gauge can non-destructively measure the thickness of non-conductive coatings on metal surfaces and non-ferromagnetic metal coatings on ferromagnetic metals (e.g. iron, nickel, cobalt, etc.), including measuring the thickness of iron, stainless steel surface paint or galvanized layer, measuring the thickness of aluminum, copper surface paint or plastic film.

PG1102 is with an external probe version; the gauge can be equipped with a variety of separated probes for easy replacement.


  • Car paint thickness detection
  • Ship manufacturing 
  • Electroplating 
  • Mental anti-rust treatment 
  • Film thickness detection
  • Metal parts processing
