The ‌GESTER GT-D02A-1 Air-Cooled Light Fastness Tester‌ is a professional xenon arc instrument for testing colorfastness and light aging of textiles, paint, rubber, plastics, paper, etc. It features a 2500W xenon lamp, multi-mode operations (spray, light-dark cycles, sample rotation), and individual sample timing. With a 25-55°C temperature range, 10-95%RH humidity control, 12 ISO/9 AATCC sample holders, meets international standards such as ISO 105-B02 and AATCC TM16, it offers stable, efficient performance for QA and R&D labs.

The GESTER GT-D02A-2 is an advanced, industrial-grade Air-Cooled Light Fastness Testing Machine engineered for high-volume lab environments. Featuring a powerful up to 3300W xenon arc lamp system, it provides superior irradiance stability and a wider temperature/humidity control range than entry-level models. color touchscreen and multi-mode climate simulation (spray, revolution, light/dark cycles), the GT-D02A-2 delivers the most realistic environmental aging data. this xenon tester is the professional standard for high-accuracy quality control in textile and polymer industries.
