Mold for coating thickness gauge, inspected before assembly.
Coating thickness gauge has the characteristics of small measurement error, high reliability, good stability and easy operation.
It is an indispensable testing instrument for controlling and ensuring product quality.
It is widely used in manufacturing, metal processing industry, chemical industry, Commodity inspection and other inspection fields.
Magnetic thickness measurement method
Suitable for thickness measurement of non-magnetic conductive layers on magnetically permeable materials. Magnetic materials are generally: steelironsilvernickel. This method has high measurement accuracy.
Eddy current thickness measurement method
It is suitable for measuring the thickness of non-conductive layers on conductive metals. This method has lower accuracy than the magnetic thickness measurement method.
Ultrasonic thickness measurement method
This method has not been used to measure coating thickness in China. Some foreign manufacturers have such instruments, which are suitable for measuring the thickness of multi-layer coatings or when neither of the above two methods can measure it. However, they are generally expensive and the measurement accuracy is poor. not tall.
Electrolytic thickness measurement method
This method is different from the above three methods. It does not belong to non-destructive testing. It needs to destroy the coating layer. Generally, the accuracy is not high, and it is more troublesome to measure than the other methods.
Radiation thickness measurement
This kind of instrument is very expensive (generally more than 100,000 RMB) and is suitable for some special occasions.
