About Ultra Voilet Conditioning Chamber
The GLOBE Ultra-violet Conditioning Chamber consists of a chamber made of aluminium sheet and fitted with a lamp to give ultra-violet radiations and a spray nozzle to give a water spray on the helmet under conditioning.
The helmet is exposed to ultra-violet radiations from a suitable lamp located vertically above the axis of the helmet.
The spray nozzle is supplied with water from a built in reservoir at a controlled rate through a pump, control valve, and a rotameter. Water is sprayed on top of the helmet from the nozzle located on one side of the chamber. The water is collected after being sprayed on the helmet in the reservoir to give a closed cycle.
In order to expose the helmet to uniform distribution of ultra-violet radiations and water spray, it is placed over a turntable, which is rotated with the help of an electric motor.
A time totalizer is provided to indicate the total time of ultra-violet radiation / water spray.
The chamber is kept on an angle iron stand. The apparatus is finished in shore blue matalic painting on the outside to give it a corrosion resistant finish. Various components that come in contact with water during the test are made from non-corrodible materials.
Advanced Accelerated Weathering TestingDesigned for accelerated weathering, the Ultra Violet Conditioning Chamber uses UVA and UVB fluorescent lamps to simulate the effects of sun exposure, moisture, and temperature on materials in a controlled setting. This makes it essential for manufacturers and researchers who need to assess durability and aging in products, coatings, or materials.
Precision and Flexibility for Reliable ResultsThe programmable digital timer supports up to 9999 hours of testing with customizable light/dark/wet cycles. Adjustable humidity (2098% RH) and temperature (ambient to 70C) settings ensure tests can be tailored to specific requirements. The chambers high resolution and accuracy confirm that each samples response to test parameters is reliably measured, enabling detailed analysis.
FAQs of Ultra Voilet Conditioning Chamber:
Q: How does the Ultra Violet Conditioning Chamber simulate real-world weathering conditions?
A: The chamber utilizes fluorescent UVA/UVB lamps, programmable temperature and humidity controls, and adjustable light/dark/wet cycles to mimic natural weathering processes. These features enable accelerated laboratory testing of materials under conditions similar to prolonged outdoor exposure.
Q: What kind of samples and specimen sizes can be tested in the chamber?
A: Up to 48 samples can be tested simultaneously, with standard specimen sizes of 75 x 150 mm. The specimen tray is made of anodized aluminum and can be customized depending on sample requirements.
Q: When should I use the programmable digital timer?
A: The digital timer allows users to set precise start and stop times for testing cycles, supporting durations up to 9999 hours. This feature is ideal for setting long-term or intermittent exposure cycles to match specific accelerated aging protocols.
Q: Where is the best application for this UV conditioning chamber?
A: This chamber is best used in laboratories and industrial material testing facilities where evaluating the durability, UV stability, or accelerated aging of products, parts, or coatings is required. Its robust construction and programmable features make it suitable for intense testing environments.
Q: What is the process for setting up a customized test cycle in the chamber?
A: Test cycles are programmed via the digital LCD panel. Users can select desired UV wavelength (313 or 340 nm, based on model), humidity, temperature, test stroke, and cycle duration. The chamber then maintains those parameters automatically throughout the testing period.
Q: How does using this chamber benefit my accelerated weathering studies?
A: By offering precise control over test parameters and simulating prolonged environmental exposure in a compressed time frame, the chamber enables quicker, more reliable assessment of material durability and UV resistance, facilitating informed decisions on product quality and longevity.
