Installation and testing of ultraviolet germicidal lamps

Ultraviolet sterilization and disinfection lamps use a special instrument for measuring ultraviolet rays-ultraviolet irradiance meter. The ultraviolet lamp is placed horizontally during the test, and the detector of the ultraviolet irradiance meter is placed at a vertical distance from the center of the lamp tube. One meter away from stray light. The UV germicidal lamp needs to be turned on for a period of time, and the measured data is more reference after the light source is stable.

The general ultraviolet irradiance meter is composed of a measurement display and a detector (ie, a probe). Considering that the detector needs to be placed 1m below the vertical of the light source during the measurement, the new LS126C ultraviolet irradiance meter has a small The strong magnet of the block is convenient for the fixing of the detector during the measurement process. As long as the metal object that the magnet can attract is placed at the corresponding position, the detector can be firmly fixed, and then the test can be facilitated.

Installation and testing of ultraviolet germicidal lamps

The ultraviolet light emitted by the ultraviolet sterilization lamp is an invisible light, and the wavelength of 253.7nm can play a good sterilization effect. This is because the absorption spectrum of light waves by cells has a regular pattern, and the largest ultraviolet ray at 230 ~ 280nm Absorbed, the absorbed ultraviolet rays actually act on the genetic material of the cell, that is, DNA, which acts as a kind of actinic.

Personal safety when using a germicidal lamp: Since ultraviolet rays will kill cells, it should be careful not to directly irradiate human skin to avoid injury when ultraviolet disinfection.

The ultraviolet sterilizer needs to have a time accumulation reminder function and an intensity alarm function, so as to remind the user to replace the ultraviolet lamp in time。
