How to calibrate the standard color plate of the colorimeter? The colorimetric standard data attached to the standard color palette is provided by the metrological verification department. The general method of metrological verification is:
The paint film coating has a protective and decorative effect on the substrate. Due to the different thickness of the coating, its protective performance will also be very different. In order to accurately assess the thickness of the film without damaging the performance of the film, you can use a film thickness measuring instrument to verify it. This article will bring you a method for measuring the film thickness. How to verify the film thickness? The film thickness measurement is to use a standard thickness gauge calibration thickness gauge to measure the coating thickness (so in most cases there is no problem of comparing the test piece). The standard test piece used for calibrating the instrument must have a clear value and meet...
1. UV energy meter UV energy meter is also known as UV Joule meter, ultraviolet energy meter, etc. It is used to measure the UV energy value of different light sources. It is mainly used for the energy of UV drying equipment in low-purification spaces. The application scope is as follows: UV ultraviolet dryer, each A variety of manual exposure machines, semi-automatic exposure machines, fully automatic exposure machines, suitable for PCB, FPC, metal etching, other printed circuit boards, image transfer processes. Especially for printing machines to ensure that the printing and drying process achieves ideal quality control.
Linshang has upgraded the multi-probe UV meter LS125 with the following five major upgrades: 1. After the upgrade, the materials and dimensions of the host and probe have been changed. 2. After the upgrade, there are 9 probes to choose from, with more UVCLED probes and UVALED-X1 probes for testing UVC band LED light sources than before. Newly upgraded multi-probe UV irradiometer
The shortwave UVC meter is dedicated to the detection of shortwave UVC ultraviolet radiation intensity. At present, ultraviolet disinfection technology is applied in many industries, including modern epidemic prevention, medicine, food disinfection, pure water treatment and photodynamics; Utilizing specially designed high-efficiency, high-intensity and long-life UVC band ultraviolet rays to irradiate flowing water, various bacteria, viruses, parasites, algae and other pathogens in the water are directly killed to achieve the purpose of disinfection. However, in the process of ultraviolet radiation sterilization, it is required to ensure the intensity of ultraviolet radiation. The intensity of ultraviolet radiation is unstable, which...
Coating thickness testing standard The various properties of the coating must be based on the thickness of the coating as a parameter, and many coatings must have the same thickness to be comparable. The coating thickness test stipulates that the minimum thickness of a layer of colored coating is not less than 0.0035 inches and the maximum is not more than 0.006 inches. The maximum thickness of the two-layer coating should not exceed 0.012 inches. When coating thickness detection is not required for the design, the allowable deviation of the total thickness of the coating dry paint film is generally -25 microns. The coating thickness tester helps to control the fine coating thickness measurement to meet the specifications when there are...
In the industry of used car appraisers, the data measured by the paint film meter is only used as auxiliary data for vehicle evaluation, and the appearance inspection can not only rely on the measurement of the paint film meter, but also needs to be judged based on the experience of the appraiser. After all, the road is one foot high and the magic is high. Now more and more accident cars are specially "facelifted" after repair, so it is necessary to choose some reliable platforms when buying second-hand cars.

Coating measurement of hardware components—a must-have for mil thickness tester Abstract: The surface of hardware parts is often sprayed with a layer of paint to protect the internal metal and prevent outside air and oxidants from entering. Paint coating thickness gauge can be said to be a must-have artifact in the hardware manufacturing industry. In the traditional sense, hardware materials refer to five metals: gold, silver, copper, iron, and tin. With the development of manufacturing technology and technology, hardware components in modern society are often sprayed with paint on the surface to meet the needs of different construction projects. Many hardware furniture, daily-use hardware components, and engineering hardware...
LS221 coating thickness gauge is also called coating thickness meter and paint thickness meter. It is a professional instrument for measuring the thickness of metal surface coatings. The host and the probe adopt a separate design, which is convenient for viewing data while testing under complex test conditions. It can be used in the laboratory and engineering field.
