Touch screen control type of building materials flammability test furnace
Scope of application:
Touch Screen Controlled Building Materials Flammability Test Furnace
Constructed with a stainless steel chamber, it features controllable automatic sample lifting, adjustable burner advancement, and other functions. This high - configuration testing instrument for building materials combustion grades is strictly manufactured in accordance with the national standard GB8626 - 2007.
The Building Materials Combustibility Test Furnace is a vertical testing device where the sample is directly impacted by a small flame to determine the flammability of building products. Adopting the Kleinbrenner principle, it assesses the combustion performance of Grade B building materials (i.e., determines the flame - retardant combustion performance/Grade B of building materials) under the direct impact of a vertical small flame.
Product function characteristics:
1.Ergonomic Design: Fully automated touchscreen operation for all testing procedures, with data storage and historical access capabilities.
2.Servo Motor - Driven Sample Frame: Features controlled, automatic lifting.
3.Adjustable Ignition Source: Allows for precise adjustment of the flame.
4.Stainless Steel Chamber: Constructed from 1.5mm - thick stainless steel plate.
5.Dual - Angle Observation: Equipped with two tempered heat - resistant glass doors for convenient and practical testing observation.
6.High - Pressure Automatic Ignition: Ensures durable and reliable combustion.
7.45 - Degree Automatic Tilt: The ignition source can automatically tilt at 45 degrees.
8.Precision Flame Control: The flame height is adjusted using a precision control valve.
9.Multi - Directional Movement: The frame can move up, down, forward, and backward.
10.Sample Clips: Comes with two sample clips.
11.Flame Measurement Ruler: Included for accurate flame measurement.
12.High Automation: Delivers accurate experimental data and is easy to operate.
13.Dimensions: 835mm (W) × 400mm (D) × 815mm (H).
14.Material: Made of stainless steel.
15.Ventilation System: The bottom of the chamber has a flat natural vent composed of 2.5cm×2.55cm square vents (made of 1.5mm - thick steel plate, 50mm high) to ensure smooth air circulation.
