As a non-contact instrument, the film thickness instrument does not have to worry about causing damage to the product during the entire use process, and does not have to worry about causing radiation to the human body. The instrument has a very wide range of applications and has become a popular instrument in the market. So what are the differences between a film thickness gauge and a thickness gauge? The following by Shenzhen Liyi Technology company for everyone to see:

1. Take the relationship literally

Literally, many people will think that the film thickness meter and the thickness meter are an instrument, in fact, it is not, in simple terms, the two should be a dependency. That is to say, the former belongs to one of the latter categories, in addition, the moderately priced film thickness meter has a slight advantage in price.

2. Different principles

Film thickness meter is mainly used to measure the thickness of coated film, thin sheet and other materials, the measurement range is wide, the accuracy is high, with the main characteristics of data output, British conversion, automatic power off, zero at any position and so on. The principle of the handheld is eddy current and magnetoresistance, and the principle of the desktop includes many kinds of inductance principle.

3. Boss classification

The thickness meter of the film thickness meter is classified into many categories according to the principle, including ultrasonic thickness meter, laser thickness meter, pressure thickness meter, X-ray thickness meter, white light interference thickness meter, mechanical contact thickness meter and electrolytic thickness meter.

4. Application field

Film thickness meter is widely used in metal processing industry, manufacturing industry, chemical industry, commodity inspection and other fields, in these fields its use is very large. It can be used to detect mass-produced parts, can detect thin coatings on tiny areas, can measure functional coatings in the electronics industry or semiconductor industry, can also be used for fully automatic measurement, such as the measurement of printed circuit boards and so on.

Film thickness instrument is not only an indispensable testing instrument to control and ensure product quality, but also a common testing instrument for various pipelines and pressure vessels in production equipment, the reason why there are so many uses, the key is that it has easy operation, small measurement error, high reliability, good stability and other outstanding characteristics.
