BGD 862 Big Xenon Climate Testing Chamber
Description
BGD 862 is a multi-function big xenon light accelerated weathering testers which is equipped with one piece high power （6.5KW）water-cooling xenon lamp, its exposure area arrive 6,500cm2
Powerful functions and reliable test results
◆ Meet with all international standards of xenon test.
◆ Equipped with ATLAS xenon arc lamp , filter and components, ensure to get high and same running parameters. Test results have a good reliability and repeatability comparing with import machines.
◆ Automatic rotating drum-type sample rack with three floors structure maximizes exposure uniformity over all specimens
◆ 6,500cm2 exposure area , can hold different shapes and sizes samples.
◆ Can set the cumulative energy （total irradiance energy）obtained by sample to finish a test procedure.
◆ Advanced cooling system for xenon lamp and intelligent air system.
◆ Chinese or English operation window
Can set and control automatically many test parameters
◆ Irradiance energy can be set and accurately controlled（340nm，420nm，300nm～400nm，300nm～800nm）. The “Closed-Loop” control system can monitor and automatically compensate the change of light intensity caused by ageing or other factors.
◆ Working room temperature, BPT（black panel temperature）and BST（black standard temperature）can be set and controlled automatically. With high precision Pt 100 temperature sensor, all these temperatures could be monitored accurately.
◆ Working room relative humidity can be set and controlled automatically. With ultrasonic wave humidifying system, the working room can obtain more stable and uniform humidity distribution.
◆ Can set spray way to sample（front spray or back spray）, spray time and spray interval time.
