The Sentry series of fixed gas detectors, designed by our company, are low-power gas detectors utilizing high-performance gas sensors and microcomputer technology, combined with excellent low-power design. They offer advantages such as power saving, intuitive display, good repeatability, long service life, magnetic installation, wire-free, simple maintenance, and convenient operation. The detectors are battery-powered and can upload gas concentration information, battery level, and abnormal type information to the control host via wireless communication such as LoRa, 4G, and NB-IOT, either periodically or upon event (alarm) triggering. Combined with system software, it enables maintenance operations such as statistics, querying, and backup of gas concentration information at various monitoring points on site
