304 Stainless Steel Environmental Test Chambers , Industrial UV
Lamp Aging Tester
1. Product description
UV lamp aging testing chamber is applicable for the sunlight
resistant test of nonmetallic materials and aging test of
artificial light sources. A variety of industrial products can
make the reliability test, and this product can simulate the
product in the sun, rain, humidity and dew conditions, including
damage caused by bleaching, color, brightness down, powder, crack,
blur, brittle, intensity decreased and oxidation.

3. Chamber Structure:
Accelerated Weather UV test machine
The inner bladder of the chamber is made of imported high-class
stainless steel plate while the outer bladder is made of SUS 304
steel plate.
The heating mode adopts inner bladder trough type heating with its
rapid temperature rise and even temperature distribution.
4. Control System:
Adopts black aluminum plate to connect temperature sensor and
adopts black board temperature meter to control heating so as to
ensure more stable temperature.
The radiometer probe is fixed so as to avoid the frequent
installation and disassembly.
The radiation quantity adopts the special UV irradiatometer with
high-precision display and measurement.
The radiation intensity is not more than 50W/m2.
The illumination and condensation can be controlled independently
or alternating and circularly.
5. Test Specimen Mounting:
Accelerated Weather UV test machine
The standard test specimen holder accommodates 2 panels 75×150mm.
The test panels are actual the side wall of the chamber. To
properly seal the chamber, it is important to have every panel
holder filled with specimens or blank panels and to have panel
holders in place.
