Spontaneous combustion test device

The invention relates to a spontaneous combustion test device. An introduction pipe, a flow meter, and an illumination unit are housed in a housing unit. A gas is introduced into an internal space ofa main body part in which a sample is housed by means of the introduction pipe. The flow of the gas flowing in the introduction pipe is prompted according to the height of a floating ball in a conicalpipe of a flow meter. Light is irradiated to the flow meter from the illumination unit disposed so as to face the front surface of the housing unit with the flow meter interposed therebetween. The flow meter can be visually recognized from the outside through the front face of the housing unit. 本发明涉及自燃试验装置。导入管、流量计以及照明部收纳于壳体部。利用导入管向收纳有试样的主体部的内部空间导入气体。根据流量计的锥形管内的浮球的高度提示在导入管流动的气体的流量。从以隔着流量计而与壳体部的正面相对的方式配置的照明部向流量计照射光。流量计能够通过壳体部的正面从外部视觉辨识。
