UV provides two methods of wet simulation. The most widely used method is condensation, which is the best way to simulate outdoor wet erosion. All UV models can run the condensation cycle. Because some application conditions also require the use of water spray to achieve practical results, so some UV models can run the condensation cycle can run the water spray cycle

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.
