Description
Fluorescent UV resistant climate (Weatherability) chamber using fluorescent UV lamp as the light source, by simulating UV radiation and condensation in the natural sunlight to tests the material accelerated weathering to obtain material weathering results. It can simulate UV, rain, high temperature, high humidity, condensation, darkness and other environmental conditions of natural climate, by reproducing these conditions, combined into a loop, and let it complete cycles automatically.

Features
◆ user-friendly design

  1. External and interior are made of corrosion resistant stainless steel, aluminum alloy sample rack, easy to install and operate.
  2. 8 pcs of 40W UV lamp imported from U.S., lamp life up to 5000 hours.
  3. Adopt imported PLC touch screen controller (SIEMENS), easy to observe and operate.
  4. Test chamber is equipped with four irradiance sensor to achieve reproducibility, uniformity and attenuation effects of UV detection and monitoring, automatic calibration. (Standard configuration)
  5. With automatic water supply system, used return scroll type sinks drainage, which is simple and convenient, with water level display and low water level alarm function.

◆ Touch screen controller (SIEMENS)

  1. 9.7-inch touch screen, can displays a variety of data, menu-driven user interface, easy to understand, observe and operate.
  2. Irradiance, temperature, humidity, rain cycles can be set and displayed visually.
  3. Touch screen can display all control parameters and automatic fault diagnosis information.
  4. Built with kind of industry standards, also it can be customized the settings according to user requirements; (can be set 10 segments)
  5. With data processing capabilities for test data and playback process provide a strong guarantee.

◆ UV source

  1. Used United States imported 40W UV lamp, relative to other types of lamps, quality and stability, spectral power distribution will not end with the lamp decay caused by aging, service life up to 5000 hours, the benefits are more test results can be repeated, and reduce lamp replacement and reduce operating costs.
  2. Meet test standards UV lamps (UVA-340, UVB-313 source) can be optional.

◆ Irradiance automatic monitoring and control system

  1. Test chamber is equipped with four irradiance sensor to achieve reproducibility, uniformity and attenuation effects of UV detection and monitoring, automatic calibration. (Standard configuration)
  2. Standard radiation meter monitoring can be traced back to the national or international metrology organizations, to ensure the accuracy and stability of irradiance. (Optional)

◆ Sprinklers

  1. Spray uniformity adjustment: Using the manual control function of the controller observed the situation in the open state of the spray, which is regulated or replace the nozzle.
  2. Spray status monitoring: equipped with sprinklers, extreme changes in temperature and rainfall spray device simulation erosion when it rains, spray evenly.
  3. Equipped with drainage collection tray for easy tank drainage needs.
  4. Effectively simulate the sample surface rain and temperature shock aging effect.
