Advantages of coating thickness gauges

Zero stability:
All coating thickness gauges require a calibration zero before measurement and can be zeroed on the instrument's calibration plate or uncoated workpiece. The stability of the instrument zero is a prerequisite for accurate measurement. After a good thickness gauge is zeroed, it can keep the zero position without drifting for a long time, ensuring accurate measurement.
No calibration required:
In addition to zero calibration, most thickness gauges need to be calibrated with standard chips. To measure a range of thicknesses, use a range of standard gauges. Mainly can not meet the linear accuracy of the full range. Not only is the operation cumbersome, but it also increases the systematic error due to the surface roughness of the standard sheet.


Temperature compensation:
The measurement of the thickness of the coating is very much affected by the temperature. Measuring the same workpiece at different temperatures gives a large error. Therefore, a good thickness gauge should have an ideal temperature compensation technology to ensure measurement accuracy at different temperatures.
Functional use:
1. Measuring the thickness of non-magnetic coating on ferromagnetic (Fe) metal substrates such as steel and iron, such as paint layers, various anti-corrosion coatings, coatings, powder coating, plastics, rubber, synthetic materials, phosphating layers, chromium , zinc, lead, aluminum, tin, cadmium, etc.
2. Measure the thickness of all non-conductive layers on non-ferromagnetic (NFe) substrates such as copper, aluminum, and stainless steel.
