Small, simple and economic Bench-top xenon lamp weathering test chamber. It uses a low power air-cooling xenon lamp to produce enough big irradiance energy in a small space. Moreover, through a special catoptrical system to ensure every exposure sample get the homogeneous irradiance distribution.
Equipped with extended UV filters, thus permit UV which is below the normal cut-on of natural sunlight to pass（equal to simulate sunlight which doesn’t come through atmosphere）.They are used to produce faster or more severe test results. This test is called as “Artificial Accelerated Weathering Test”
Operator can set all required test parameters （Irradiance, test time, BPT etc）through the touch screen, and can check its running status at any time. All running parameters can be exported to computer through the USB interface.
Bench-top xenon lamp test chamber Test Principle
Bench-top xenon lamp weathering test chamber Artificial weathering of coatings or exposure of coatings to filtered xenon-arc radiationis carried out in order to obtain the degree of change in a selected property after a certain radiant exposure H, and/or the radiant exposure which is required to produce a certain degree of ageing. The properties selected for monitoring should preferably be those which are important for the practical useof the coatings. The properties of the coatings exposed are compared which those of unexposed coating prepared from the same coating materials at the same time and in the same way (control specimens)or with those of coatings exposed at the same time whose behavior during testing in exposure apparatus is already known (reference specimens).
Xenon Lamp light can emulate the effect of sunshine. During the test, radiation energyand temperature are controllable.These tests generally applied in the fields of paint and coatings, automotive industry,plastic, wood, glue, etc…
Bench-top xenon lamp weathering test chamber Characters
◆Xenon Lamp Test Chamber– Small Size, easy to install, use and practically maintenance-free.
◆The xenon light source correspond with international standards; ensure reproducibility and comparability of testing results.
◆ Irradiance energy can be accurately controlled. The “Sun Eye” control system can automatically compensate the change of light intensity caused by ageing or other factors.
◆ Users can easily calibrate and adjust the irradiance or the blackboard temperature by themselves.
◆ With High precision Pt100 Temperature sensor. Blackboard temperature is auto-controlled during the whole process
◆ Alarm function for protection：Over temperature, over heating load,big error for irradiance, auto shut-down protection when opening door.
◆ Touch screen and user-friendly operation interface allow operator to set the test parameters and monitor all the test process easily.
◆ Specimen mounting and evaluation is fast and easy With unique slide-out specimen tray
◆ Real-time data can be collected and recorded. The incidental USB connector allow users to copy the test data into a USB drive, achieving unattended operation.
