The waterproof light meter probe UVC-WP independently developed by Linshang can be used with a UV light meter to detect the intensity of UV germicidal lamps in water treatment equipment.
The sewage treatment equipment is placed in water, so the waterproof UV light meter for detecting the ultraviolet lamp also needs to be put into the water test, which requires the water treatment germicidal lamp detector to be waterproof.
UV disinfection is the use of ultraviolet light to inactivate the microbes to achieve the purpose of purifying water. Ultraviolet light refers to electromagnetic waves having a wavelength between 100 nm and 400 nm, and ultraviolet light is invisible light. According to the wavelength, it can be divided into UVA (315-400nm), UVB (280-315nm), UVC (200-280nm) and UVD (100-200nm).
UVC can effectively destroy the DNA structure of the organism to achieve the sterilization effect. This is because UVC can be well absorbed by the genetic material DNA and RNA of microorganisms. When the DNA and RNA in the microorganism absorb enough ultraviolet energy, the internal nucleic acid strand (pyrimidine) is interrupted and rearranged to form thymine. The dimer prevents the replication of DNA and RNA, and the microorganism is inactivated and cannot replicate itself. This is the principle of ultraviolet disinfection - the principle of inactivation.
The ultraviolet lamp used in the sewage treatment equipment is generally a high-power low-pressure mercury lamp, in which 254 nm is the main peak, and the luminous efficiency is the strongest. When UV disinfection, the intensity of UV light also needs to be strictly controlled. The intensity of ultraviolet light must reach a certain standard to achieve the effect of germicidal lamp. Therefore, a waterproof light meter is required. Since the sewage treatment equipment is placed in water, the waterproof UV light meter for detecting the ultraviolet lamp tube also needs to be put into the water test, which requires the water treatment germicidal lamp detector to be waterproof.
Linshang LS125+UVC-wp multi-probe waterproof light meter has introduced a waterproof UV test probe for detecting sewage treatment equipment. It can be directly placed in water for detection and can be waterproof to 1 meter deep. This waterproof probe is mainly used to detect the UVC intensity of 254nm. With a range of 0-200,000 uW/cm2, it is fully capable of testing the strength of high-power water treatment germicidal lamps.
