3 important auxiliary accessories required by UV aging test chamber

1. Purified water filtration device: Everyone should know that the test equipment needs to use pure water or filtered water, so the UV Aging Test Chamber can filter the water by configuring a purified water filtration device in the water supply box under the test equipment. Usually installed with automatic water replenishment valve and manual water replenishment drawer. If a filter device is installed, connect the automatic water replenishment valve to the pressure water source. Once the water tank is short of water, open the water inlet solenoid valve of the equipment. , the filtered tap water will enter the water storage tank.

2. Lighting automatic protection device: Due to the particularity of the test equipment, in order to avoid the danger of exposure to ultraviolet rays when the equipment is opened during the test, the photoelectric proximity switch can be installed on the front and rear doors of the UV Accelerated Weathering Tester. Once opened accidentally The door of the box can automatically turn off the UV light irradiation function, and when the door of the box lid is closed, the UV light will resume irradiation.

 

3. Using a radiometer: You can measure the real-time irradiance by using this instrument. At present, the instrument has a hand-held and an installed type. The hand-held radiometer is used in combination with the probe and the display screen. If the box door is opened when irradiating, select a radiometer with the same wavelength band and range on the display screen according to the wavelength of the lamp tube
