GESTER International Co.,Limited adheres to the company tenet of Quality Comes First during the development process. We introduce a set of quality management system that is featured by quick turnover and specific clarification of responsibility and accountability. From the incoming material sourcing through assembly to ex-factory inspection, we designate quality assurance personnel to conduct detailed checking. Now, thanks to the strict execution of the system, we can obtain ISO certification and gain a pass rate of above 90%, ensuring a stable quality of the product.
Gester Instruments now is growing rapidly both at home and abroad. Gester Instruments provides a wide range of demattia flex tester for customers. The electrical safety tests for Gester Instruments Instruments gloves cutting tester have been professionally conducted. It is mainly tested for its continuity, voltage, and amperage. Its stainless steel raw materials make it easy to clean. As a result of the implementation of a complete quality management system, products meet the most stringent quality standards. It can function normally even under low temperature and high pressure.
We will increase our positive social impact through a range of sustainable strategies. We source sustainable raw materials, implement strict control on water usage, wastes discharge, and greenhouse gas emissions.

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

Firefighter turnout gear plays a critical role in protecting firefighters operating in extreme environments involving high temperatures, flames, radiant heat, and convective heat. Its thermal protective performance directly affects firefighter safety and survival during fireground operations. This article explains how to test firefighter turnout gear thermal protection through Thermal Protective Performance (TPP) testing. It introduces the scientific principle based on the Stoll curve, outlines key influencing factors such as heat flux intensity and exposure time, and reviews internationally recognized standards including NFPA 1971 and ISO 17492. The article also highlights the testing advantages of the GT-RC02 TPP Thermal Protection Tester, which provides accurate, stable, and standards-compliant evaluation of flame-retardant protective clothing materials under combined radiant and convective heat exposure.
Footwear soles and uppers endure thousands of flex cycles during use, risking premature cracking, delamination, or chipping if material resistance is inadequate. This technical analysis details two critical international standards:
1. ISO 5402-1: Specifies the flexometer method for testing leather flex resistance under repeated bending.
2. ISO 17694: Defines test methods for footwear upper and lining flex resistance, simulating real-world bending stress to assess long-term durability.
