Ensure protective plates and cylinders move freely without obstruction.
FAQs
1. What is the purpose of the Glove Thermal Insulation Tester?
The Glove Thermal Insulation Tester is a precision instrument designed to evaluate the thermal insulation performance of gloves when exposed to high temperatures. By using a heated brass cylinder and accurate temperature sensors, it measures how fast the glove surface temperature rises. The data collected is repeatable and reliable, allowing manufacturers and R&D teams to assess the protective capabilities of heat-resistant gloves in household, industrial, automotive, and kitchen applications. This helps ensure compliance with international standards and safety regulations.
2. How does the tester operate to measure glove thermal insulation?
The test involves placing a glove sample on a polyethylene mounting plate equipped with thermocouples. A preheated brass cylinder is then dropped onto the sample under controlled gravity, and the temperature rise is recorded in real time. The system uses high-precision Omega sensors and transmitters to measure temperatures accurately. The cylinder automatically returns, and the thermal protective plate moves to maintain safety. Real-time data display and automatic curve plotting on a connected PC allow operators to generate detailed test reports for evaluation.
3. Which gloves and materials can be tested with this system?
The tester is suitable for evaluating household oven gloves, industrial gloves, automotive gloves, and kitchen gloves. It can assess materials used in heat-protective applications across various industries, supporting both R&D and quality control departments. By simulating real thermal exposure, it ensures that gloves meet required manufacturing specifications, verify thermal resistance, and comply with international standards such as EN 407. ISO 12127. and ASTM F1060.
4. What features make this tester precise and reliable?
The system uses a combination of a servo-controlled brass cylinder, high-precision Omega sensors, and a 32-bit multifunction mainboard for accurate motion and temperature control. Real-time data acquisition, automatic curve plotting, and test report generation improve operational efficiency. The system also includes automatic cylinder return, protective plate movement, and a touchscreen HMI interface with Chinese/English menus. These features ensure precise, repeatable measurements while maintaining operator safety.
