ZN-T desktop UV weather resistance test chamber delivered to your door

The damage caused by sunlight and moisture to materials causes inestimable economic losses every year. The UV accelerated weathering testing machine can reproduce the damage caused by sunlight, rain and dew. The equipment performs the test by exposing the material to be tested to a controlled alternating cycle of sunlight and moisture while increasing the temperature. The equipment uses ultraviolet fluorescent lamps to simulate sunlight, and can also simulate the effects of moisture through condensation or spray. This equipment refers to the UV aging test in the standard "Silicone Structural Sealant for Construction". It can also be used for other tests on irregular samples related to UV standards. The equipment uses four lamp tubes and is top-mounted.

br/> , The lighting control time can be set arbitrarily within a thousand hours
, During operation or setting, if an error occurs, a warning signal will be provided
, French Schneider components
, Philips rectifier and starter (to ensure that the UV lamp can be lit every time it is turned on)
5. Light source
The light source uses a series of ultraviolet fluorescent lamps with a rated power of The top of the box
The spectral energy of the lamp that meets the test standards is mainly concentrated around the wavelength
6. Safety protection device
If the door of the box is opened when the lamp is on, The machine will automatically cut off the power supply to the lamp and enter a balanced state for cooling to avoid harm to the human body
. Over-temperature protection in the box. When the temperature in the box is too high, the machine will automatically cut off the power supply and enter a balanced state for cooling
7. Equipment acceptance This equipment refers to the UV aging test in the standard "Silicone Structural Sealant for Construction".
