HYG-308 SF6 leak online detection and alarm system is an intelligent online detection system designed and developed to provide personal health and safety protection for the staff in the distribution equipment room equipped with SF6 equipment in accordance with the current situation of emphasizing safe production in the power system.

The system mainly detects the SF6 gas content and oxygen content in the ambient air. When the SF6 gas content in the environment exceeds the standard or lacks oxygen, it can alarm in real time, and automatically open the ventilator for ventilation. It has many rich functions such as temperature and humidity detection, voice prompt of working status, remote alarm, historical data query and so on.
