HD-QT-1280/1450A/1550 Wall Steady State Heat Transfer Testing Machine

Product Information

The wall steady-state heat transfer testing machine is based on the principle of using a protective heat box method in accordance with the "GB/T13475-2008 Determination, Calibration, and Protective Box Method for Thermal Insulation Steady State Heat Transfer Properties"

Manufacturing production. It is mainly suitable for measuring the heat transfer coefficient and thermal resistance of various building walls, as well as for detecting the heat transfer of various panel insulation materials, insulating glass, laminated glass, etc

Thermal coefficient.

Product Features:

1. Intelligent microcomputer control, accurate and reliable data.

2. Independently developed PC version wall testing software with comprehensive testing and data management functions.

3. The box adopts double-layer color steel plates with 100mm thick polyurethane as the wall, greatly reducing losses.

4. The specimen frame adopts heavy-duty universal wheels, which are more convenient to operate and more sturdy and durable.

5. Adopting an integrated operation control cabinet, the computer is embedded in the upper casing of the control cabinet, making operation more convenient.

6. A brand new hardware platform and high-speed data processing chip provide assurance for experiments.

7. The connection between the cold box/specimen frame/protective box adopts high-strength latch type quick clamps, which are easy to operate, solid and durable.

8. Each box is wrapped with self-made hard sheet metal parts, making the box more sturdy, with a simple and beautiful appearance design.
