Product overview
LFZ-XW xenon UV weathering environmental testing chamber for accelerated weathering tests of paints, coatings, plastics, rubber, textiles, materials, cosmetics, pharmaceuticals and food-contact containers. Available in Economic, I and II models with selectable exposure areas and optional radiometer control.

Key features

• Mirror-reflection system provides a large, uniform exposure area to increase irradiance and reduce required exposure time.
• Slide-out sample tray accepts plates, bottles, test tubes, Petri dishes and other special samples for easy loading.
• Interchangeable xenon lamp (compatible with U.S. brand); lamp life up to 1500 hours.
• SIEMENS PLC touch-screen controller for program setup, monitoring and data handling.

Touch screen controller (SIEMENS)

• 9.7-inch touch display with menu-driven interface for intuitive operation.
• Visual setting and display of irradiance, black panel temperature and rain cycles.
• Shows all control parameters, automatic fault diagnosis and lamp attenuation prompts for stable, uniform irradiance.
• Supports selectable industry-standard controllers and up to 10-segment programs.
• Built-in data processing for test records and process playback.

Irradiance automatic monitoring and control system
Automatic irradiance monitoring and control available (optional radiometer models CR20 or RM20).
