UV Weathering Test Chamber, 45℃~80℃, No Spray Function, Shanghai Yiheng Scientific Instruments Co., Ltd (CAT#: STEM-MDT-0070-YJL)

UV Weathering Test Chamber, 45℃~80℃, No Spray Function, model B-UV-I(Original: LZW-050A) is manufactured by Shanghai Yiheng Scientific Instruments Co., Ltd. The outer shell of this product adopts the cold-rolled plate spraying process, the inner tank adopts SUS304 stainless steel material, and the aluminum alloy material sample rack is easy to install and operate. There are 4 irradiance sensors in the front and back of the test box, which can detect and monitor the reproducibility, uniformity and attenuation of ultraviolet light, and can be automatically calibrated (standard). It has an automatic water replenishment system. The drainage system uses a vortex type and a sedimentation device to drain the water. The drainage is simple and convenient, and it has the functions of water level display and low water level signal alarm.

◆ Touch Screen Controller (SIEMENS)
● 9.7-inch touch screen, one-screen display of various data, menu-type operation interface, simple and easy to understand, easy to observe and operate.
● Irradiance, temperature, humidity, rain cycle, etc. can be set and displayed intuitively.
● The touch screen can display all control parameters and automatic diagnosis fault information.
● The industry standard is built into the controller, which can be selected by users with different industry needs, and can also be customized according to user requirements; (10 segments can be set)
● With data processing function, it provides a strong guarantee for the test process data and playback.

◆UV light source
● Using 8 40W UV lamps imported from the United States, compared with other types of lamps, the quality is stable, the spectral power distribution will not be attenuated with the aging of the lamps, the service life is as high as 5000 hours, the advantage is that more tests can be repeated As a result, there are fewer lamp replacements and lower operating costs.
● Ultraviolet lamps (UVA-340, UVA-351, UVB-313 light sources) that meet the test standards can be selected by users.
◆Irradiance automatic monitoring and control system UV test chamber without irradiance sensor detection has long been a thing of the past...
● Break through the defect that the irradiance cannot be monitored and controlled in the existing domestic aging test box, and reduce the irradiance attenuation and test error caused by the aging of the lamp tube.
● There are 4 irradiance sensors in the front and back of the test box, which can detect and monitor the reproducibility, uniformity and attenuation of ultraviolet light, and can be automatically calibrated.
Professional irradiance calibration
● Equipped with self-developed irradiance calibrator, which can be calibrated simply and quickly. Can be traced back to national or international metrology agencies to ensure the accuracy and stability of irradiance.

◆Spraying device
● Spraying uniformity adjustment: Use the manual control function of the controller to observe the spraying status in the state of opening the door, so as to adjust or replace the spray head.
● Equipped with drainage collection tray to facilitate drainage in the box.
● Effectively simulate the aging effects of rain and temperature shock on the surface of the sample.
