Chamber Structure:
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.
 
 
 
 
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:
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.
