UV weathering test chamber

DSZ-UV

Fluorescent UV lamps closely simulate the UV band of sunlight. With temperature and humidity control, the chamber reproduces the conditions that cause fading, loss of gloss, cracking and peeling.

UV wavelength range: 280–400 nm
Lamp life over 1,500 hours: 8 lamps
Effective exposure area: 380,000 mm²
