The BGD 864 is a compact, simple and economical xenon test chamber. It uses a low-power, air-cooled xenon lamp to generate high irradiance in a small space. A special reflector system ensures that all samples receive homogeneous irradiance
The BGD 864 is equipped with extended UV filters that transmit UV radiation below the normal cut-on of natural sunlight (equivalent to simulated sunlight that has not passed through the atmosphere). This produces faster and more severe test results. This type of test is known as an “artificial accelerated weathering test”
The operator sets all required test parameters (irradiance, test time, black panel temperature, etc.) via the touchscreen and can check the running status at any time. All running parameters can be exported to a computer via the USB interface
In addition, the chamber can be equipped with various optional modules, such as water spray, humidity control and water immersion, to simulate working conditions during light exposure
Features
Cost-effective performance: a competitive purchase price, low-cost lamps and low operating costs make this weathering chamber highly cost-effective. Even small laboratories can now afford xenon-arc weathering tests.
Compact and user-friendly: small footprint, easy to install and use, and virtually maintenance-free
Standardised light source: the xenon light source complies with international standards, ensuring reproducible and comparable test results
Lamp compatibility: compatible with both domestic and imported xenon lamps. Lamp service life is approximately 1,500 hours, and lamp replacement is simple
Fast test results: outdoors, products are exposed to maximum-intensity direct sunlight for only a few hours per day. This chamber exposes specimens to irradiance equivalent to midsummer noon sunlight 24 hours a day, enabling rapid ageing of samples
Accurate irradiance control: a closed-loop control system automatically compensates for changes in light intensity caused by lamp ageing or other factors
Easy calibration: users can calibrate and adjust the irradiance and black panel temperature themselves.
Precise temperature control: a high-precision Pt100 sensor controls the black panel temperature automatically throughout the entire test
Safety alarms: alarms for black panel over-temperature, large irradiance deviations and low air pressure, plus automatic shut-off when the door is opened
Touchscreen operation: a user-friendly touchscreen interface allows the operator to set test parameters and monitor the entire test
Real-time data logging: test data is recorded in real time and can be copied to a USB flash drive via the built-in USB port, allowing unattended operation
Optional auxiliary cooling: an auxiliary cooling air system is available as an option. It lowers the chamber temperature to a minimum of 20 °C, making the chamber suitable for xenon-arc testing at ambient or low temperatures
