Operation method and usage skills of coating thickness gauge
When using a coating thickness gauge, pay attention to the operating steps and usage skills of the instrument, which can greatly increase the service life and measurement accuracy of the coating thickness gauge.
Although the price of the coating thickness gauge is not very high, it is ultimately a "helper" of our property and work. Pay attention to the following points to not only extend the service life of the instrument, but also obtain accurate measurement results. Precautions for using ultrasonic thickness gauge:
When using a coating thickness gauge for measurement, the probe must be perpendicular to the surface of the object being measured;
2. Do not drag the probe during measurement, as it will not only cause wear on the probe but also result in inaccurate measurement results;
3. During measurement, the probe wire should not be excessively bent or shaken at the position where the probe is connected (for split type coating thickness gauges), as this will affect the testing effect and result in inaccurate and stable measurement results;
4. Try to ensure that the coating thickness gauge is used and kept by a dedicated person;
5. If you feel that there is a significant deviation in the measurement results, please first use the five randomly equipped plastic calibration sheets for one round of testing. If the deviation is far from the allowable error, it may be due to a problem with the instrument itself and it needs to be returned to the factory for maintenance. Remember not to disassemble and repair it on your own.
Development status of coating thickness gauges
Thickness measurement is one of the important projects for testing the physical properties of coatings. With the development of new engineering materials, the application of microelectronics technology, and the standardization process, coating thickness measurement technology has developed rapidly both domestically and internationally in the past decade. At the same time, various types of thickness gauges that adopt various principles, have a wide range of applications, possess high-tech content, and are becoming increasingly intelligent have emerged, and their scientific testing methods have been increasingly improved, effectively promoting a leap in engineering physical testing.
At present, in advanced industrial countries, coating thickness measurement technology standards have formed their own systems, and there are multiple specifications of coating thickness gauges that can simultaneously consider dual principles and meet the requirements of multiple test method standards. Therefore, it greatly expands its application fields and marketing markets, and also provides reference and guidance for China to adopt advanced foreign technology standards, accelerate the standardization process, and promote the upgrading and replacement of domestic instruments. According to incomplete statistics, China has formulated more than 40 international and specialized methods or instruments related to coating thickness measurement technology so far. The creation and improvement of this standard system will strictly regulate the quality requirements for coating thickness detection and instrument development, effectively promoting the overall development of thickness measurement technology.
