Gester Instruments is one of the most professional shore hardness tester suppliers R&D and operation teams in China. As one of Gester Instruments's multiple product series, ozone test chamber series enjoy a relatively high recognition in the market. Color is the number one factor that must be considered when making Gester Instruments Instruments fabric testing equipment, as it is the first element of the buyer's reaction, because of its color appeal, often choosing or rejecting a bedding. High impact resistance is the special property of the product. This product can greatly help people get rid of smelly feet thanks to its bacteria resistance. People will feel peace in mind with a clean feet environment. Adopting stainless steel as the key materials, it is not easy to crack.

Do you know the Down Proof of Fabrics?
Down-proof performance is crucial for fabrics in down jackets, duvets, and comforters. Poor downproofing leads to feather leakage, reducing warmth and aesthetics. The GT-C41 Down Proof Testing Machine evaluates fabric tightness to prevent feather penetration, ensuring high-quality production. Learn how it works and why it matters.
Water Resistance Testing Standards and Methods
Textile water resistance testing evaluates fabrics through three primary methods: hydrostatic pressure (measuring water penetration resistance), spray rating (assessing surface water repellency), and water repellency tests (quantifying water absorption). Hydrostatic pressure testing is critical for high-performance applications like outdoor apparel and diving gear, while spray rating evaluates surface staining for rainwear. Water repellency tests, such as the Bundesmann method, determine overall

Heat Contact Machine GT-C101-The Ultimate Selection Guide

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.
