Field smoke intensity testing device

The invention discloses a field smoke intensity testing device, and relates to a smoke intensity testing device. Comprising a mounting box, and a high-precision smokemeter, a hot air fan, a thermometer and a controller which are mounted in the mounting box. Wherein a test channel of the high-precision smoke meter penetrates through and extends to the outer side of the mounting box and is used for collecting smoke from the field. The hot air output end of the hot air fan faces the high-precision smokemeter and is used for heating the high-precision smokemeter. The thermometer is used for monitoring the temperature in the installation box. The controller is used for collecting the temperature signal output by the thermometer, comparing the temperature signal with a set temperature threshold value and controlling the hot air fan to work in a first power state, a second power state or a third power state according to a comparison result. According to the high-precision smoke meter, all-directional heating of the
