UV Sterilizer lamp is a lamp made by the special effect of ultraviolet rays. The sterilization intensity of the ultraviolet lamp is proportional to the radiation intensity of the ultraviolet lamp. In order to ensure the disinfection effect of the ultraviolet lamp, the intensity test of the ultraviolet lamp must be carried out to determine whether the quality of the ultraviolet lamp is qualified.

First, install the UV Sterilizer lamp on the measuring rack, and mark the vertical center position of the lamp under the irradiation table. The distance between the lamp and the irradiation table can be adjusted up and down to meet the radiation intensity required by the test. Turn on the UV lamp, wait for five minutes, the lamp tube is stable, and adjust the UV radiation intensity of the central test point of the irradiation platform under the lamp according to the intensity indicated by the standard color block on the indicator card. .

Next, during the irradiation test, irradiate the discolored area of ​​the indicator card on the measuring stand. Each group of ten indicator cards is lit for one minute, and three groups of each intensity are lit, a total of 30 cards. instruction card. Immediately after irradiation, observe the irradiated indicator card with the naked eye, and compare the color of the color block in the discolored area with the color of the corresponding standard color block. When the matching rate of the color blocks in the area and the standard color blocks, as well as the test results of the indicator card and the measurement results of the illuminometer all exceed 90%, it can be judged as qualified.

In order to know whether the radiation intensity of the UV Sterilizer lamp meets the standard, the radiation intensity of the ultraviolet lamp should be checked every six months. The ultraviolet radiation intensity should be greater than 70uw/cm2. If it is less than 70uw/cm2, the lamp should be replaced immediately.
