The EPK MikroTest S3 measures the thickness of enamel, plastic, and rubber layers on steel.
The MIKROTEST Coating Thickness Gauge measures the thickness of all non-magnetic coatings on steel (e.g. lacquer, powder coat, plastic, zinc, copper, tin and nickel). Fast, accurate and non-destructive, MICROTEST has been the most widely used instrument for the automatic determination of coating thickness for more than 30 years. Germany's "know-how" shows that it has the highest level of magnetic cladding Thickness Gauge in terms of process technology and precision.
EPK MikroTest S3McCourt Coated Thickness Gauges comply with DIN EN ISO2178, DIN 50982, ASTM B 499, E 376, ASTM D 1186, ASTM G12, ASTM B 530, BS5411, ISO2361 standards.
MIKROTEST OPERATES FULLY AUTOMATICALLY. It has the following very good characteristics when in use:
1) Automatic measurement will not occur misoperation;
2) Simple setup and measurement;
3)No calibration required;
4)No batteries or other power sources are required;
5)Automatically report the thickness reading;
6)With a non-destructive probe, a little bit of measurement;
7)The metal armor is suitable for frequent outdoor operation and use, and is protected from mechanical impact;
8)Resistant to mechanical shock, acid and solvent corrosion;
9)The balancing device eliminates the influence of gravity and can accurately measure in any direction and in the tube.
