First, the product overview 

SZ10-KRQT-S1A wireless flammable gas detector (referred to as "NB-IoT combustible gas") is a self-developed NB-IoT wireless indoor combustible gas detector for detecting flammable gas leakage and preventing damage caused by gas leakage. When the detector detects that there is a flammable gas leak and reaches the alarm concentration set by the detector, the red LED of the detector flashes and an alarm sounds. At the same time, the alarm signal of the detector is reported to the far wireless via the wireless base using the NB-IoT network. Monitor the platform so that monitoring personnel can handle it in time. 

Second, product features

● Low cost: NB-IoT mode, using carrier network, no need to set up base stations, reducing system cost;  
● Easy to install: long-distance wireless communication, simple wall mounting, simple and convenient, greatly reducing construction time;  
● Easy maintenance: intelligent Operation and maintenance, real-time monitoring of equipment operating status, timely detection of faults;
