Xenon Test Chamber/weather ometer
Introduction
Weather-Ometer and Fade-Ometer tester adopts water-cooled xenon lamp. This instrument using argon arc lamp simulation control ideal natural climate and solar and other experimental conditions to to test the color and performance of textile dyes. It can also test the material Anti-aging properties, which can ensure good reproducibility and reproducibility on the basis of accurate test product life. Besides, it is widely used in plastics, paint coating, ink, packaging, automotive materials, photochemical materials, pigment dyes and textiles and other industries. The equipment has been certified by several international standards organizations.
Applications
Weather-Ometer and Fade-Ometer with their advanced digital control systems, represent monumental achievements in applying digital and optical technologies in easy-to-use laboratory weathering instruments. The Series is approved by many OEMs in the textiles, paints & coatings and plastics industries as the exclusive platform to deliver accurate, reproducible and repeatable results for predicting service life. The Series has been certified CE, UL, CSA, ISO and EN compliant
Features
