Product Description


   Coating Thickness Gauge MT4500  is a portable paint coating thickness meter for fast, accurate and non-destructive measurement of the thickness of non-magnetic coatings (such as paint and film) on metal substrates. This product has seen wide application in manufacture, metal working, chemical industry, commodity inspection and other fields, both for laboratory and engineering environment, and is essential for material protection major.



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.

  MT4500 coating thickness gauge uses both 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) and Eddy Current Method to measure the non-conductive coating on a non-magnetic metal substrate (such as aluminum, chromium, copper, zinc, nickel, 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.

Magnetic Method

 Eddy Current Method (NF-type probe) 
  When the probe contacts the cover layer, the probe and non-magnetic substrate forms Eddy Current and gives feedback to the coil inside the probe. The thickness of the cover layer can be derived by measuring the feedback.
