Digital Chrome Dft Film Plastic Car Paint Coating for Thickness Gauge Meter Tester
The instrument is a type of portable measuring gauge, capable of measuring rapidly, nondestructively, and precisely the thickness of coating and cladding material. It is suitable for on site as well as for laboratory uses. Via the using of different probes, many sorts of measuring can be satisfied by the gauge. It can be applied comprehensively to manufacturing, metal processing and chemical profession as well as to commercial inspection. It is indispensable for the major of materials protection.
The instrument caters for the demands as follows:
GB/T 4956-1985
GB/T 4957-1985
JB/T 8393-1996
JJG 889-95
JJG 818-93
