HD-SBI Single Unit Combustion Testing Machine for Building Materials or Products

Product Information

This testing machine is a testing device used to test the reaction of building materials or products (excluding flooring materials) to fire in individual combustion tests, in order to determine their physical properties. This testing machine strictly meets the requirements of the national standard (GB/T20284) for testing conditions.

Product Features:

1. The overall interior of the host is covered with flame-retardant insulation board, and the smoke hood adopts a double-sided structure on the outside, filled with asbestos board for insulation, resulting in minimal overall heat loss.

2. The whole machine is made of iron plate and steel frame, with electrostatic spraying technology and 2 observation windows.

3. Adopting high-precision mass flow controller and imported temperature sensor, the test data is accurate.

4. External dust removal equipment has good smoke purification effect and long maintenance cycle.

5. The measurement and control system consists of a 7-inch touch screen and a 19 inch industrial tablet computer. The software human-computer interaction interface is simple, friendly, and beautiful. The upper computer software has functions such as real-time data display, status display, and warning prompts, and can complete data report printing and export.
