| (Manhole / Confined Space) Wireless Multi-parameter Gas Monitor This terminal is an advanced instrument with wireless upload function, which is used to monitor the gas concentration in the underground confined space of the city. The terminal uses laser sensor and microcomputer technology, combined with excellent low-power technology design, with saving power, display intuitive, good repeatability, long service life, easy to install, easy maintenance, convenient operation and so on. The terminal uses battery power, and can upload the gas concentration information, abnormal type and other information to the data center through the wireless network in a fixed time or in an event (alarm) mode through the local existing cellular communication network. Combined with the system software, the statistics, query and backup of the gas concentration information can be realized. The terminal is suitable for pump-suction interval collection monitoring and early warning of gas concentration in urban underground confined spaces such as gas valve wells, water supply and drainage wells, electric power wells and communication wells. Product advantage Gas concentration state monitoring, immersion detection, temperature detection; 2) Embedded integrated circuit + intelligent software; 3) Mobile NB-IOT communication module, telecommunications NB-IOT Internet of Things card, underground pipe network underground communication; 4) Unattended, remote intelligence real-time accurate alarm; 5) The electronic map displays location, basic information, and real-time status; 6) Internet of things NB-IOT wireless communication technology, cloud data interaction; 7) Remote monitoring interface, mobile phone, computer client, WeChat, SMS alarm; 8) Excellent low-power design Battery powered, battery available for 3 years, maintenance-free; 9) Real-time data, historical data, curve display; 10) Platform data export function. 11) Intrinsically safe equipment that can be used in explosion-proof areas; 12) IP68 protection level, dustproof and waterproof.
