Ultraviolet disinfection is widely used, for example: hospitals, schools, nurseries, movie theaters, buses, offices, homes, etc. It can purify the air and eliminate moldy odors. In addition, it can generate a certain amount of negative oxygen ions. In public places, disinfection by UV can prevent some germs from spreading through the air or the surface of objects.

At present, all UV lamp manufacturers are developing long-life lamps, such as the cold cathode series of UV lamps. We also need to use professional equipment to monitor the UV intensity and whether it causes harm to the human body, so we need an UVC light meter. 

When the UVC light meter measures the intensity of the UV germicidal disinfection lamp, a special instrument for measuring the UV lamp must be used-the UVC light meter. Turn on the UV lamp, wait 5 minutes for the light source to stabilize.  The detector of the UVC light meter is placed at a distance of one meter below the center of the lamp tube, while shielding stray light. The UV germicidal lamp needs to be turned on for a period of time and the measured data after the light source is stable is more informative.

UVC light meter

Generally, the UVC light meter of ultraviolet lamp is used to measure the ultraviolet light intensity. When measuring the intensity of ultraviolet light, the detector needs to be placed 1m below the light source. The light receiving hole of the instrument is facing up to accept the ultraviolet light source. It also comes with a one-meter hook, so you only need to place the instrument on the hook and hang the hook in the center of the tube. Then you can easily test.

The ultraviolet light emitted by the ultraviolet tube germicidal lamp is an invisible light. The wavelength of 253.7nm can play a good sterilizing effect. This is because the absorption spectrum of light waves by cells has a regularity and ultraviolet rays at 230 ~ 280nm have maximum absorption, the absorbed ultraviolet light actually acts on the cell's genetic material, that is, DNA, which plays a photochemical role. Pay attention to the personal safety when using germicidal lamps: Because ultraviolet rays can kill cells, we must take care not to directly irradiate human skin during ultraviolet disinfection to avoid injury.
