Contact Heat Transmission Tester

The Contact Heat Transmission Tester is a precision instrument designed to evaluate the heat transfer resistance of protective clothing, thermal gloves, and other fire-resistant materials. By simulating direct contact with a high-temperature surface under controlled pressure, it measures the time required for the material temperature to rise by 10°C, providing an objective metric of thermal protection performance.

Application

(1) Medical Protective Clothing: Helps develop and screen garments that minimize heat accumulation and wearer discomfort during extended use, reducing the risk of heat stress.

(2) Industrial and Fire Protection Clothing: Evaluates thermal insulation performance under high-temperature exposure, ensuring worker safety and compliance with fire protection standards.

(3) R&D and Material Testing: Supports development of new thermal protective materials and verification of multi-layer protective ensembles.

(4) Quality Control: Confirms consistency of thermal resistance across production batches.
