Xenon Arc Weather Ometer SI4000

Introduction：

SI4000Xenon Arc Weather Ometer utilizes a xenon lamp to simulate ideal natural climate and sunlight conditions. It is suitable for testing the aging resistance of materials in a variety of industries, including textiles, wire and cable, plastics, coatings, and building materials. Its exceptionally cost-effective performance rivals the industry's CI series weathering chambers, enabling precise testing of product lifespan while ensuring excellent repeatability and reproducibility.

Working Principle：

1. This instrument simulates natural climate and artificial sunlight using a xenon lamp by varying temperature, humidity, and spray conditions. It is suitable for testing color and performance changes in materials across a wide range of industries. It reliably simulates full-spectrum sunlight to test the aging resistance of materials.The SI Series is a water-cooled solar tester featuring light energy circuit control, irradiance monitoring, humidity circuit control, blackboard temperature circuit control, multi-point energy monitoring, a reliable deionized water system, and various filter combinations.

2.A 6500W xenon lamp and ultrasonic humidification system provide a test environment for simulating tests under varying solar spectra and various climatic conditions, ensuring stable testing and highly repeatable test results in a short period of time.

Compliance with Standards：

The SI4000 Xenon Arc Weathering Tester complies with nearly all major international, national, and industry test standards, including ASTM, ISO, SAE, AATCC, IEC, and GB. The following is only a partial list. For more information and a more precise list of compliance standards, please contact a sales representative.

General Purpose:ASTM G155 / MIL-STD-810H

Automotive:ASTM D7869 / ISO 105-B06. -B10 / JASO M346. M351 / SAE J2412. J2527

Coatings:ASTM D6695 / ISO 16474-2

Textiles:AATCC TM 16. 169 / ISO 105-B02. -B04 / Marks & Spencer C9. C9A

Plastics:ASTM D2565 / ISO 4892-2

Other:IEC 60068-2-5 (Photovoltaic), ASTM D7356 (Acid Etch), ASTM C1442 (Sealants), ICH Guidelines Q1B (Pharmaceuticals)

Key Features：

1. Intelligent Touchscreen Control Panel:PLC control system, more efficient and reliable. A programmable 7-inch color LCD touchscreen enables multiple functions, including control, monitoring, calculations, and data display.

2. Powerful Software:The enhanced control system can handle both complex custom programs and simple pre-programmed tests. The user interface features simple, easy-to-understand icons. Irradiance, temperature, and humidity can be programmably adjusted in steps to meet diverse testing requirements.

3. Comprehensive Protection:The instrument features irradiance monitoring, lamp power monitoring, water quality monitoring, temperature monitoring, water level limit protection, water flow monitoring, dry burn protection, and leakage protection to ensure equipment and personnel safety.

4. Large Testing Area:The imported xenon lamp and the new water-cooled xenon lamp cooling system provide excellent cooling performance and low cooling water consumption, complying with national environmental protection guidelines. The large test chamber can test up to 65 samples at a time, and the rotating sample rack ensures consistent exposure across all samples. This improves testing efficiency and conserves water. 5. Closed-loop irradiance monitoring and automatic adjustment: The instrument can test multiple wavelengths and is automatically calibrated regularly using an irradiance calibration device.

6. Benchmarking against industry-leading technology:The SI4000 xenon arc weathering test chamber replaces the Atlas CI4000 xenon arc weathering tester of the same model. It can be installed with genuine Atlas lamps and offers the same spectrum and performance as the Atlas xenon arc weathering tester, making it a perfect replacement. The company also provides complete installation and after-sales service.

Applicable Industries：

Applications include, but are not limited to:

1. Automotive:Testing the aging resistance of vehicle exterior and interior materials, paints, and rubber components

2. Building materials:Evaluating the weather resistance of products such as roofing tiles, exterior wall coatings, and plastic window frames

3. Packaging:Verifying the stability of plastic films, paper, and labels under long-term sunlight

4. Textiles:Studying the resistance of dyes, coatings, and fibers to UV fading
