Product Description


   Thickness Gauge MT220  adopts magnetic induction technique for measurement. The compact design perform fast, precise and non-destructive digital coating measurement and plating on steel magnetic conductor . It is widely used on manufacturing, workshop, chemistry or quality control  fields.


This device meets the following criteria:

GB/T 4956鈹1985 non-magnetic coating thickness measurement on magnetic metal substrate, Magnetic Method.

GB/T 4957鈹1985 non-conductive coating thickness measurement on non-magnetic metal substrate, Eddy Current Method.

GB/T 8393-1996  Magnetic & Eddy Current coating thickness measurement.

  The product uses Magnetic Method to measure the non-magnetic coating (such as aluminum, chromium, copper, enamel, rubber, paint, etc) on magnetic metal substrate (such as steel, iron, alloy and hard magnetic steel, etc).

 Magnetic Method (F-type probe) 
  When the probe contacts the cover layer, the probe and magnetic substrate forms a closed magnetic circuit; Due to the presence of non-magnetic coating, magnetic resistance changes. The thickness of the cover layer can be derived by measuring the change.
