Ultraviolet light meter detects the intensity of ultraviolet radiation, and is used to measure the intensity of ultraviolet radiation in the fields of photochemistry, flaw detection, ultraviolet light source, plant cultivation, large-scale integrated circuit lithography, and polymer material aging.

Ultraviolet light is ultraviolet radiation, which is electromagnetic radiation with a wavelength of 100-400nm. It refers to the intensity of ultraviolet radiation per unit area. The instrument commonly used to detect the intensity of ultraviolet radiation is called an ultraviolet radiometer, also called an ultraviolet illuminance meter. Although it is called an illuminance meter, it has nothing to do with illuminance. Illumination studies the visible light that the human eye can see. The ultraviolet light meter measures ultraviolet light, which is invisible to the human eye, so it is related to the irradiance.

Irradiance is called radiant flux density and it is the integral of radiance to the solid angle. The area of the irradiance is integrated to obtain the power of the radiation.

Definition 1: Radiated energy projected onto a unit area per unit time.

Definition 2: The radiant energy received by an object on a unit time and unit surface. The unit is W / m2.

Definition 3: The radiant flux on an infinitely small bin containing the point divides the area of the bin.

Definition 4: Radiated energy projected onto a unit area per unit time. Irradiance (Ee, E) is a physical parameter, which is the amount of radiant energy received per unit area on a given surface. Unit: Watt / square meter.

The wavelengths measured by the UV radiometer are divided into UVA (320nm-380nm), UVB (280nm-320nm), and UVC(200nm-280nm). ShenZhen Xinzhibang UV Radiometer LS125 can detect UVC, UVB, UVA various wavelengths. It is widely used in sterilization, curing, pharmaceutical factory testing, sewage treatment, disease control center, non-destructive testing, welding arc testing, ultraviolet aging experiment testing and other industries.

Shenzhen XZBELEC Inst. & Eqpt. Co., Ltd company is established in 2011, Shenzhen xinzhibang Inst. & Eqpt. Co., Ltd is a professional enterprise of instruments and meters.

CERAMIC GRAINS

The alumina abrasive having a microcrystalline structure obtained by the gel method is called the ceramic grains. Through special processing, each grain has thousands of tiny crystals. This structure brings the very good self-sharpness performance of the grains, which can continuously reveal new and sharp cutting edges.

RIKEN RMC Ceramic grains are very dense, rough, strong and sharp. When worn, they will produce a sharp cutting edge similar to the knife edge. Therefore, the ceramic grains will have a lower cutting temperature and lower burnt than the ordinary alumina when sanding hard to sand materials. It can be keeping sharpness for a long time with low loading. So that will bring you less total downtime and longer life.

Ceramic grains products could process into kinds of shapes, like belts, sand discs, sheets. The grains character decide that products have longer sanding life, higher cutting force and higher sanding efficiency performance.

Ceramic abrasive grain belts and sanding discs could bring you rapid cutting on difficult-to-sand materials such as aerospace, aerospace alloys and forged steel. The unique ability of ceramic abrasives increase production and reduces labor costs. RIKEN RMC Ceramic grains products also have a good performance in general sanding in auto repair, steamships, and aluminum alloys.

Ceramic abrasive is a new abrasive with microcrystalline structure prepared by gel sintering. It does not use smelting method and uses Al2O3 below 5 microns. In the presence of acid, some of the oxide is added to produce gelatin, which is made into granules. The raw material is strict, and the content of sodium oxide is less than 5%. It is characterized by non-smelting and crystallization within 3 microns.

Ceramic abrasives are hard and tough. Fine crystal shape can make Abrasives fall off regularly at different levels, make self-sharpening orderly, keep the sharpness of the whole abrasive, and have good processing effect.

Working conditions are equally important. Temperature and pressure are more important. Crystals are destroyed one by one to achieve self-sharpening.

It is first used to coat abrasives, which is 3-5 times higher than ordinary corundum (ordinary 100, zirconium corundum 207, ceramic abrasive 333).

At present, the world famous ceramic abrasives manufacturer include Saint-Gobain, 3M, Tebuck , VSM and Hermes. American 3M company is called "Cubitron", and its maximum crystallization is less than 3 micron.

Norton company is called SG abrasive, its crystal form is several microns; German Hermes company is called CB abrasive, its maximum crystallization is less than 5 microns. The crystal type of CX abrasive in Japan is called 1 micron, but in fact it is less than 3 micron.
