Instrument introduction:

Usage overview: 

The fluorescent ultraviolet light weather resistance test chamber uses fluorescent ultraviolet lamps as the light source. By simulating ultraviolet radiation and condensation in natural sunlight, the material is subjected to accelerated weather resistance tests to obtain the results of the material's weather resistance. It can simulate the environmental conditions such as ultraviolet, rain, high temperature, high humidity, condensation, and darkness in natural climates. By reproducing these conditions, merge them into a cycle and let it automatically perform the number of cycles.

Features: 

◆ Humanized design 

● The shell and inner liner are made of corrosion-resistant stainless steel, and the aluminum alloy sample holder is easy to install and operate.

● 40 imported from 8 original US W Ultraviolet lamp tube, the service life of the lamp tube reaches 2000 hours.

● Adopted for import PLC Touch screen controller (SIEMENS)，Easy to observe and operate.

● Four irradiance sensors are installed in front and behind the test chamber to detect and monitor ultraviolet light reproducibility, uniformity and attenuation, and can be automatically calibrated. (Standard )

● It has an automatic water replenishment system, and the drainage system uses a vortex type and a deposition device to drain water. The drainage is simple and convenient, and it has water level display and low water level signal alarm functions.

◆ Touch screen controller (SIEMENS) 

● 9.7The touch screen is displayed in one screen with various data, and the menu-style operation interface is simple and easy to understand, making it easy to observe and operate.

● Irradiance, temperature, humidity, rainfall cycle, etc. can be intuitively set and displayed.

● The touch screen can display all control parameters and automatic fault diagnosis information.

● Industry standards are built into the controller, which can be selected by users with different industries, and can also be customized according to user requirements.； (Can set 10 sections )

● It has data processing function, providing strong guarantees for experimental process data and playback.

◆ Ultraviolet light source 

● Imported from the United States original 40 W Ultraviolet lamp tube, the service life of the lamp tube reaches 2000 hours.

● UV lamps comply with test standards ( UVA-340，UVB-313 Light source) is available for users to choose from.

◆ Automatic irradiance monitoring and control system 

● Break through the defects that the irradiance of existing domestic aging test chambers cannot be monitored and controlled, and reduce the irradiance attenuation and test errors caused by lamp aging.

● Four irradiance sensors are installed in front and behind the test chamber to detect and monitor ultraviolet light reproducibility, uniformity and attenuation, and can be automatically calibrated.

● Standard irradiometer monitoring (purchase) can be traced back to national or international metrological institutions to ensure the accuracy and stability of irradiance.

◆ Spraying device 

● Spray uniformity adjustment: Use the controller's manual control function to observe the spraying condition in the door opening state, thereby adjusting or replacing the spray head.

● Spray status monitoring: The machine is equipped with a spray device. The spray device simulates the drastic temperature changes and rainwater erosion during rain, and sprays evenly.

● Equipped with a drainage collection tray to facilitate drainage in the box.

● Effectively simulate the aging effect of rainfall and temperature impact on the surface of the sample. UV test chambers without irradiance sensor detection have long been history.

◆ standard 

● SAE J2020  ● PREN 1062-4   ● ISO4892-3  ● ASTM G53  ● EN534  ● ISO11507

● ASTM D4587   ● ISO 11507  ● ASTM D4329  ● ASTM D5208  ● ISO 4892-3
