Introduction
Product Overview
The Contact Heat Resistance Tester is a professional laboratory instrument designed to evaluate the thermal protection performance of materials under direct high-temperature contact. By measuring the time required for a specimen’s surface to rise 10°C under controlled pressure and heating conditions, this tester provides a quantitative assessment of thermal resistance.
It is widely used for developing and testing firefighter suits, heat-resistant gloves, protective workwear, and other high-temperature safety materials.
Application Fields
Firefighter protective clothing
Heat-resistant gloves and mitts
High-temperature industrial protective textiles
Thermal insulation materials for safety applications
Laboratory testing of heat-resistant fabrics
Quality control in PPE manufacturing
Standards Compliance
This instrument fully complies with international standards for contact heat resistance testing, including:
