Function: microcomputer control, computer operation;

Annular furnace heating temperature calibration: display time, temperature curve and actual measured temperature comparison chart;

The smoke concentration and smoke production rate of the material are automatically calculated after setting;

Real-time display of the rotation chart of the angular velocity of the squirrel cage;

The running time of the annular furnace can be set arbitrarily; It has the functions of manual and automatic ring furnace fast forward and backward.

Test principle: The test standard is formulated based on the results obtained in China in the quantitative preparation of material flue gas methodology in the laboratory and the experimental mouse inhalation flue gas poisoning test methodology and the practical experience of tobacco toxicity evaluation of materials. It is one of the important criteria for judging the combustion performance grade of A2, B, and C composite (sandwich) materials.

Main features: The design of the building material smoke toxicity test equipment is simple, the operation is convenient, and the automatic adjustment mode of the test chamber is directly controlled by the software, which greatly saves manpower and material resources. Among them, the mouse cage rotates flexibly on the scaffold, and there is no fixed stationary point. The poison kit is made of colorless and transparent plexiglass material, which has good sealing performance and avoids the leakage of smoke.
