SV-TT4100-TT3100 Coating Thickness Gauge
Overview
The instrument adopts the magnetic and eddy current principle to measure in a non-destructive way .The instrument is a portable thickness-measuring meter, it can measure the thickness of coating and plating rapidly, non-destructively and precisely.It can be used both in lab and the work site.This instrument can be widely used in the inspection fields, e.g. manufacturing, metal processing, chemical industry and commodity inspection, etc.It is a gauge essential for the material protection.
The instrument adopts the magnetic and eddy current principle to measure in a non-destructive way
Magnetic way (type F probe)
measure the thickness of non-magnetic coatings on magnetic metallic base (e.g. zinc, aluminum, Cr. Copper, rubber, paint, coating on the base of steel, iron, alloy and hard magnetic steel etc.)
Eddy current way (type N probe)
measure all electrically insulating coating layers,such as lacquer,Varnish, paint,anodizing coating on nonferrous metals,also on austenitic VA steel materials.
