Using magnetic induction or Eddy current, this electronic gauge offers precision thickness measurement of non magnetic coatings such as paints, zinc etc. on steel（F：ferrous probe）, and insulating materials on non-ferrous substrates（FN：non-ferrous.）. The gauge is available with either integral or external F, N or dual FN probes. The FN probe features automatic substrate recognition to simplify operation.
Biuged offer many different types of thickness Gauges to meet with different clients’ request under different conditions.
