UV weather resistance test chamber

Purpose

UV-Lamp Weathering Test Chamber Take fluorescent UV lamp as light source to simulate the UV irradiation in natural light and condensation to conduct accelerated weathering test to the materials. It can simulate the UV, rain, high temperature, high humidity, condensate, darkness and other environmental conditions in natural climate and combine them in a circle, and carry out these circles automatically.

Chamber Structure

The spectral energy distribution of UVA-340 lamp focus on wavelength of 340nm
The spectral energy distribution of UVB-313 lamp focus on wavelength of 313nm
All lamps are imported from America with active service life of 1600~1800 hours, and the service life of 2500 hours may be achieved by irradiation adjustment
The inner bladder of the chamber is made of imported high-class stainless steel plate while the outer bladder is made of A3 steel plate sprayed with plastic.
The heating mode adopts inner bladder trough type heating with its rapid temperature rise and even temperature distribution.

Safety Protection Equipment
1.When the lamp is on, if the chamber door is opened, the machine shall cut off the power supply of the lamp 
and enter balance status for cooling automatically to prevent causing injury to human body. 
The safety door lock meets the IEC 047-5-1 safety protection requirements.
2.When the temperature in the chamber exceeds 70C±10%, 
the machine shall cut off power supply of the lamps and heater and enter balance status for cooling automatically.
