The S400-WX fixed gas detector for industrial and commercial use is a low-power gas detector designed by our company, suitable for industrial sites and commercial places. It is primarily used in environments such as gas stations, refueling stations, and storage and transportation warehouses for flammable and explosive gases, where gas concentration and gas leakage need to be detected. This advanced low-power gas detector employs a high-performance infrared gas sensor and microcomputer technology, combined with excellent low-power design. It features power saving, intuitive display, good repeatability, long service life, magnetic mounting, no wiring, easy maintenance, and convenient operation.
This detector is battery-powered and can transmit gas concentration information, battery status, anomaly types, and other information to the control host via LoRa wireless communication, either at regular intervals or based on events (alarms). When used with system software, it allows for the statistical analysis, query, backup, and other maintenance operations of gas concentration information from various monitoring points on-site.
