Yes, colour fastness to ozone is fully tested before shipment. GESTER International Co.,Limited is a quality-oriented manufacturer with great achievements in quality control. Before we tapped into the global markets, we paid less attention to the ex-factory inspection, which results in the high rejection rate of the product. Now, since we have conducted detailed quality assurance rules and set up criteria for ex-factory product quality, the pass rate of the product has increased remarkably. Customers can rest assured about the product quality by remotely reviewing our QC process.

The Heat Contact Machine GT-C101 is a specialized testing instrument designed for evaluating the heat resistance and thermal protective performance of gloves, protective clothing, and other heat-resistant materials used in high-temperature environments. In industries such as smelting, casting, welding, and glass manufacturing, workers are frequently exposed to intense heat, making accurate testing of contact heat resistance essential for ensuring safety and compliance.
GT-C101 simulates real working conditions by measuring heat transfer delay and thermal transmission under instant contact with high-temperature surfaces. Fully compliant with EN 407, EN 702, and ISO 12127-1 standards, this machine provides precise, repeatable data for manufacturers, laboratories, and research institutions. With high-temperature capability up to 500°C, advanced calorimetry, digital monitoring, and adjustable contact speed, the Heat Contact Machine GT-C101 is an indispensable tool for developing and certifying next-generation PPE and heat-insulation materials.
