In traditional society, hardware products mostly refer to appliances made of five metals: gold, silver, copper, iron and tin, commonly known as "small hardware". In modern society, with the continuous progress of manufacturing technology, the scope of hardware appliances has become more extensive, such as hardware tools, hardware parts, construction hardware and security supplies.
Since most of the hardware materials are metal, for functional use needs, such as anti-oxidation, anti-corrosion, waterproof, fire prevention, etc., or for decorative needs, the coating of hardware supplies has already become a unified recognition in the industry. But how to test the quality of hardware products under the glittering coating? How to determine the effectiveness and rationality of the coating? We believe this is the place where many manufacturers are distressed and confused. We can solve these problems with the help of film thickness gauges.
Film thickness gauge is also called coating thickness meter, coating thickness gauge, which refers to a precision instrument that uses magnetic induction, eddy current, X-ray, ultrasonic and other methods to measure the surface coating or coating thickness of an object. In actual application, the film thickness gauge can be divided into two categories: handheld and desktop. For the detection of coatings on hardware appliances, choosing a portable and reliable handheld film thickness gauge, such as the Linshang LS220H film thickness gauge, is undoubtedly a good choice.
Once you have selected a suitable film measuring instrument, then wen should know how to use it. In the actual metal plating measurement inspection process, the tester only needs to press the probe vertically on the measured object surface then with the automatic calibration function of the microchip, the results are displayed directly on the display. In the inspection process, due to the consideration of accuracy and reliability, testers often test multiple places or the same place for multiple times. Finally, we calculate the average value to reduce the impact of the error.
For the film thickness gauge itself, it is just a simple measurement tool, but for the entire hardware industry, it is a key to test the product quality and improve the product coating process. Therefore, it is necessary to choose a film thickness gauge according to different needs; it is very important to choose a film thickness gauge with accurate measurement and quality assurance according to actual needs.
