GX25 is designed to artificially reproduce indoor deterioration factors such as sunlight, temperature and humidity. GX25 exposes materials to these factors and accelerates the deterioration process to predict their lifespan in a relatively short period of time.
The light source is “2.5kW water-cooled xenon arc lamp” developed by SUGA closely resembling the sunlight and it can control the irradiance between 40W/m2 and 60W/m2 (at 300-400nm). GX25 conforms to light resistance tests for textiles, ISO, ASTM, and AATCC
Feature
1.Wide range of control for temperature and humidity GX25 conforms the option 2 and 3 of AATCC (American Association of Textile Chemists and Colorists) xenon arc test for textiles (AATCC TM169) which specifies the irradiance 40W/m2 (at 300 to 400nm), BPT (Black Panel Temperature) 77℃ and relative humidity 70%(option 2), 27%(option 3). Xenon lamp and daylight fi lter are allowed for about 2000 hours of continuous use.
GX25 can control simultaneously each of BPT and CAT (Chamber Air Temperature) used in a lot of test standards.
2. Established the Irradiance and Temperature
Direct Control System on a Specimen Plane The irradiance on the specimen plane and the black panel temperature are directly measured and controlled at the same position as the specimens as they rotate, maintaining repeatability and test reproducibility
