PID SSR Control UV Aging Test Chamber , Accelerated Weather Testing
UV Test Machine
Product description:
Accelerated Weather UV test machine is equipped with 8pcs UVA lamps,Q-test PLC controller.and this flat type uv aging chamber can
simulate the natural sunligth condition for the sunlight resistant test of nonmetallic materials and aging
test of artificial light sources.
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.
Application industry (not limited to the following):
1. Paint ink paint, resin, plastic
2. Printing and packaging, aluminum, adhesives
3. Motorcycle industry, cosmetics,
4. Metal, electronics, electroplating, medicine and so on.
Applications function:
1. Simulate the sun, rain spray and condensation resulting damage
to test the materials by exposure to sunlight with moisture and
temperature.
2. To get the results of damage after several days or weeks which
is equal to expose to outside for a few months. The damages include
fading, discoloration, brightness down, powder, crack, blur,
brittle, strength decreases and oxidation.
3. Provide reference with testing data for improvement of existing
materials, or to assess the impact of changes in product durability
and other aspects.
Test standard(inculding but not limited to... ):
Compliance with ASTM G154,GB/T16422.3-1997,etc.

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.
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.
