Application

The VIT 422 Water-Cooled Light & Weather Fastness Tester (Weatherometer) is designed to determine the color fastness and aging resistance of textiles, plastics, rubber products, and other materials by simulating natural weather conditions such as daylight, rain, temperature, and humidity. This tester replicates both light and dark cycles and environmental conditions through rack sprays and a water-cooled long-arc xenon lamp.

Standards

AATCC 16, AATCC 169, ISO 105-B02/B04/B06, ISO 4892, ASTM G155, GB/T 8427, GB/T 8430, GB/T 14576, GB/T 1865, GB/T 1766, GB/T 15102, GB/T 15104, GB/T 16422.1, GMW 3414, SAE J1960, SAE J1885, JASO M346, PV 1303, M&S C9, JIS L0843

Features

  • Digitally set light intensity with real-time monitoring and automatic adjustments to maintain stable light source conditions (optional 420nm or 300–400nm band monitoring).
  • Blackboard Thermometer (BPT) and Standard Blackboard Thermometer (BST) placed alongside the sample for accurate test condition reflections.
  • Large, colorful LCD display with multiple monitoring modes, including animations, figures, charts, and curves.
  • Independently timed sample holders allow for simultaneous testing of different samples.
  • Equipped with a water-cooled 4500W long-arc xenon lamp that closely simulates the daylight spectrum.
  • Professional water circulation system reduces operating costs.
  • Industrial cooling system for quick and smooth temperature control.
  • Ultrasonic humidifier and professional dehumidification system for stable and accurate humidity conditions.
  • Built-in self-circulation and air filtration systems minimize environmental requirements.
  • Capable of 1000 hours of continuous operation.
  • Front and back spray pattern capability for realistic environmental simulation.

Specification

  • Power: 380 V, 50 Hz, 12 KW
  • Weight: 300 Kg
  • Dimensions: 1000 x 800 x 1800 mm (L x W x H)
  • Working Modes: Simulates environmental factors like light, temperature, humidity, and rain with precise quantitative control.
  • Light Source: 4500W water-cooled long-arc xenon lamp
  • Average Lamp Lifetime: 1200 hours
  • Temperature Range: Room temperature +5°C to 48°C, accuracy ±2°C
  • Humidity Range: 30%–85% RH, accuracy ±5%
  • Test Time Control: Up to 1000 hours
  • Irradiance Range: (0.8–1.400) ±0.02 W/m² @ 420nm; (35–55) ±1 W/m² @ 300–400nm (digitally set and automatically compensated)
  • Sample Holder Size: 210 x 45 mm, with a maximum capacity of 250 samples
  • Sample Holder Rotation Speed: 1 rpm
  • Independent Sample Timing: Up to 1000 hours
  • BPT Range: 40°C–80°C, accuracy ±2°C
  • BST Range: 40°C–85°C, accuracy ±1°C
