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.
