Heat Transfer Coefficient Tester
Category：Flammability Tester
Introduction
The On-Site Heat Transfer Coefficient Tester is designed to measure the heat transfer coefficient of building envelope structures and assess heating and energy supply efficiency. The device integrates automated data acquisition and temperature measurement controlled by a host computer. The heating box is constructed with high-performance insulation materials to ensure temperature stability, and the surface is equipped with instruments to display internal temperatures. The system can simultaneously record temperature and heat flux, automatically calculate the heat transfer coefficient, and generate comprehensive test reports.
Applications
This tester is suitable for:
(1) Measuring heat transfer coefficients of walls, floors, and roofs in residential and commercial buildings.
(2) Evaluating energy efficiency and heating demand for building envelope structures.
(3) Conducting on-site building thermal performance assessments.
(4) Supporting compliance verification with national and regional building energy codes.
(5) Research and development in building insulation materials and HVAC system efficiency.
(6) Providing reference data for retrofit and energy-saving renovation projects.
