UVC light meter test UV band intensity

The wavelength range of the ultraviolet UVC band is 200-275nm. The ultraviolet band of this band is also called short-wave sterilizing ultraviolet rays, mainly because the ultraviolet rays in this band can penetrate the cell membrane of bacteria and viruses, damage the nucleic acid (DNA), and make the cells lose their ability to reproduce. To achieve the effect of rapid sterilization. Ultraviolet sterilization is mainly applied to the surface of objects. Traditional sterilization methods generally use heating, dosing and other means. However, these treatment methods take a long time, which may cause adverse changes to the treatment object and secondary pollution to the environment. Sterilization with ultraviolet radiation can completely avoid the above problems.
UVC light meter is an important instrument for measuring the intensity of ultraviolet radiation, usually composed of ultraviolet radiation probe (detector), corresponding electronic circuit and measurement data display part. Among them, the ultraviolet radiation probe converts the received ultraviolet radiation into an electrical signal, and the high electrical signal is amplified by an electronic circuit and processed accordingly after being displayed by a digital electric meter or an analog electric meter. There is a certain proportional relationship between the size of the electrical signal and the ultraviolet radiation received by the ultraviolet radiation probe. The size of the electrical signal generated by the instrument under the standard value of ultraviolet radiation is modulated by the electronic circuit to the standard value to complete the calibration of the instrument .With the development of science and technology and industry today, ultraviolet radiation measurement technology is widely used in various fields such as industry, medical treatment, bad environment, health and health, such as medical treatment, sterilization, nondestructive testing, material aging, photochemical reaction, crop diseases and insect pests Prevention and control, atmospheric environment protection, etc. have all put forward higher and higher requirements on the accuracy of ultraviolet radiation illuminance measurement and the accuracy of magnitude.The role of ultraviolet light involves many aspects, some of which have become specialized engineering issues. It is well known that ultraviolet light has disinfection and sterilization effects and has good prevention and treatment effects on some diseases. These biological functions are mainly limited to UV-B area and UV-C area. The UV-C area has a main wavelength of 253.7nm, and detection of ultraviolet radiation at 253.7nm requires a professional UVC ultraviolet radiation meter for the purple band.
