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 GT-3000 Water-cooled Light Fastness Tester is a professional-grade Weatherometer designed to simulate the most extreme outdoor conditions. this xenon weathering test chamber provides accurate simulation of full-spectrum sunlight, humidity, and rain. It is the ideal solution for industries requiring high-irradiance testing, such as automotive, coatings, and plastics. Fully compliant with ASTM G155 and ISO 105 B02 standards, the GT-3000 ensures your materials meet the most rigorous global durability requirements.

The GESTER GT-D07 Fabric Washing Fastness Tester is an industry-leading solution engineered specifically for textile laboratories and accredited third-party testing institutions. Designed to perform precision evaluation of color transfer, color change, and dry cleaning durability, this model delivers absolute data repeatability across multiple international methodologies including ISO, AATCC, JIS, and BS.

The GESTER GT-KC01-1 Veslic Rub Fastness Tester is a benchtop laboratory instrument designed to measure the color fastness and surface wear resistance of leather, footwear uppers, synthetic materials, and coated fabrics. It evaluates finish damage, color transfer, and surface breakdown under regulated cyclic rubbing with standard wool felt in both dry and wet conditions. Compliant with ISO 11640, DIN 4843, and EN ISO 20344, the GT-KC01-1 provides precise, reproducible quality control data for leather tanneries, footwear manufacturers, and automotive interior laboratories.

The GESTER GT-D04 Crockmeter Machine is a motorized, high-precision test instrument designed for high-throughput testing of textile color fastness to dry or wet rubbing. Powered by a motor-driven system with a preset electronic cycle counter (up to 9,999 cycles), crockmeter rubbing fastness tester GT-D04 eliminates human speed variability and automatically stops upon test completion. Designed for woven, knitted, and dyed fabrics, it guarantees strict compliance with ISO 105-X12, AATCC 8/165, and ASTM D6279.

The GESTER GT-KC01 Veslic Rub Fastness Tester is a robust physical testing machine designed to measure the rub color fastness, surface abrasion resistance, and finish adhesion of natural leathers, footwear uppers, synthetic materials, and coated fabrics. As a leading leather testing machine manufacturer supplier, GESTER engineers the GT-KC01 to operate strictly in accordance with ISO 11640, SATRA PM 173, and EN ISO 20344. The machine subjects pre-tensioned specimens to controlled reciprocating linear friction using standardized white wool felt pads under regulated contact loads. It serves as a classic, durable quality control solution for leather tanneries, footwear QC laboratories, and commercial testing facilities worldwide.

The GESTER GT-D09 Perspiration Tester (Perspirometer) is a standardized laboratory test apparatus engineered to evaluate the color fastness of dyed, printed, and colored textiles against human sweat, distilled water, seawater, and saliva exposure. Constructed with high-grade 316L stainless steel, the GT-D09 resists chemical corrosion caused by acidic and alkaline artificial perspiration solutions. It features dual compliance with ISO and AATCC standards, accommodates up to 42 test specimens per run, and utilizes a spring-loaded clamping frame to maintain consistent pressure across all specimen plates during oven incubation.

Premier Textile Testing Equipment Manufacturer (Nearly 30 Years Expertise) The GESTER GT-D05 Manual Crockmeter is designed to determine the resistance of colored textiles, leather, and woven materials to wet and dry rubbing. Built with a solid steel chassis and a high-temperature baking coating, GT-D05 features a pinned acrylic sample holder for rapid mounting and repeatable results. Fully compliant with major international standards including ISO 105, AATCC 8, JIS L 0849, BS 1006.
