    • coating thickness gauge


      The series of EC-666 coating thickness gauges can measure the thickness of non-ferrous metal coatings and non-magnetic insulating coatings on ferromagnetic metals (such as iron, nickel and cobalt, etc.)They are mainly used for non-destructive thickness measurement for the coatings of iron, paint or zinc on stainless steel, paint or plastic foil on aluminum and copper, etc.
      EC-666 is with internal probe combined with magnetic induction and eddy currents principle, which is with measurement range of 0~2000μm and accuracy of ±(3%+1μm), and the highest resolution is up to 0.1μm.
      EC-666 is only with one button, and it is easy to use. When you start measurement, place the probe vertically and rapidly on a suitable surface, then the device will automatically distinguish the substrate material and measure the thickness of coatings. EC-666 is with large storage capacity.
      The result will be recorded automatically during measurement. Data can be sent to computer via USB cable.
      On the base of EC-666, EC-666S is upgraded its probe and accuracy, and added new functions. EC-666S is with stronger anti-interference ability compared with EC-666, and it can work in the high electromagnetic fields environment. The accuracy of EC-666S is ±(2%+1μm), and the measurement result can be sent to the mobile APP in real-time via bluetooth.
      EC-666E and EC-666SE are the external probe version of EC-666 and EC-666S, their cable length is about 1 meter. Compare with the internal probe version, external probe devices are more suitable to work on narrower space or assembly line work.
