Jianhu Xe-3000 Xenon Arc Weathering Chamber

Overview

The Jianhu Xe-3000 Xenon Arc Weathering Chamber is an engineered environmental simulation system designed to replicate the full solar spectrum—including UV, visible, and near-infrared radiation—under controlled temperature, humidity, and wet/dry cycling conditions. Based on the principles of xenon arc irradiation, it delivers photometrically accurate spectral output that closely matches terrestrial sunlight (AM1.5G), enabling quantitative assessment of material degradation mechanisms such as photooxidation, chalking, cracking, color fading, and loss of mechanical integrity. Unlike UV fluorescent or metal halide sources, xenon lamps provide continuous spectral distribution across 290–800 nm, making the Xe-3000 suitable for accelerated aging protocols requiring fidelity to natural exposure conditions. Its rotating drum configuration ensures uniform angular exposure across all specimens, minimizing positional bias and enhancing inter-laboratory reproducibility.

Key Features

• Triple-lamp xenon arc source (1500 W × 3 or 2500 W × 3) with quartz envelope and integrated igniter circuitry for stable ignition and extended lamp life
• Programmable irradiance control system supporting narrowband (340 nm or 420 nm) or broadband (300–400 nm) monitoring; real-time digital display with auto-compensation for lamp aging
• Dual-sensor thermal management: simultaneous closed-loop control of black panel temperature (BPT) and chamber air temperature, both independently adjustable within specified ranges
• High-precision humidity regulation via motorized damper-controlled air mixing, decoupled from ambient lab fluctuations to ensure repeatability under varying facility conditions
• Integrated water quality monitoring with conductivity sensing and audible/visual alarm for low-resistivity or particulate contamination
• SUS304 stainless steel interior chamber with seamless welding, corrosion-resistant insulation, and non-reflective matte finish to minimize stray light interference
• Optional traceable calibration accessories: NIST-traceable radiometer (for irradiance validation) and certified optical filters (quartz, borosilicate, daylight, extended UV)

Sample Compatibility & Compliance

The Xe-3000 accommodates flat-panel specimens up to 120 mm × 200 mm per position on its 24-position rotating drum, supporting standard test substrates including textiles, automotive trim, coatings, plastics, elastomers, and architectural sealants. Its operational envelope meets the physical and procedural requirements of globally recognized weathering standards—including ASTM G155 (Cycle A/B/C/D), ISO 4892-2 (Method A/B), SAE J2527 (Class A/B), JIS D0205, BS EN ISO 11341, and DIN 75220. All control parameters—including irradiance setpoint, ramp rates, dwell times, humidity profiles, and spray intervals—are fully programmable and auditable, facilitating compliance with GLP and GMP documentation frameworks. The system architecture supports 21 CFR Part 11–compliant electronic records when paired with validated software modules.

Software & Data Management

Control is executed via a PID or PLC-based embedded controller with a high-resolution touchscreen interface, offering intuitive navigation through multi-stage test programs. Data logging occurs at user-defined intervals (1–60 seconds), capturing irradiance (W/m²), BPT, chamber air temperature, RH%, and lamp voltage/current. Export formats include CSV and PDF reports with time-stamped metadata, operator ID, and instrument serial number. Optional Ethernet connectivity enables remote monitoring, centralized fleet management, and integration into LIMS environments. Audit trails record all parameter modifications, user logins, and alarm events—retained for ≥18 months with automatic rollover and password-protected access levels.

Applications

• Colorfastness evaluation of dyed textiles and printed fabrics per ISO 105-B02 and AATCC TM16
• Automotive interior and exterior component qualification per GMW14124, Ford CETP 00.00-L-467, and VW PV3929
• UV stability testing of polymer-based medical device housings compliant with ISO 10993-12
• Accelerated weathering of architectural coatings under cyclic wet/dry conditions (ASTM D4587)
• Photostability screening of pharmaceutical packaging materials per ICH Q1B
• Validation of UV absorbers and HALS stabilizers in polyolefin formulations

FAQ

What spectral filters are included by default?
The base configuration includes a daylight filter (quartz inner + borosilicate outer) meeting ISO 4892-2 Class I requirements. Optional filters—extended UV, window glass, and UV-cut—are available as calibrated add-ons.
Can the Xe-3000 perform dark cycles with condensation?
Yes. The system supports fully independent programming of light/dark phases, including condensation-only segments via controlled humidification and cooling without irradiation.
Is lamp alignment required after replacement?
No. The fixed-focus optical assembly and automated lamp centering routine eliminate manual collimation; irradiance recalibration is performed via the built-in reference sensor.
How is calibration traceability maintained?
Each unit ships with a factory calibration certificate referencing NIST-traceable standards. Annual verification can be conducted using optional handheld radiometers with documented uncertainty budgets.
Does the chamber support third-party software integration?
Yes. Modbus TCP and OPC UA protocols are supported for bidirectional communication with enterprise MES or SCADA platforms.
