  • Wide-concentration multi-component hazardous gas detector and implementation method thereof
    Patent number: 11555808
    Abstract: The disclosure discloses a wide-concentration multi-component hazardous gas detector and an implementation method thereof, solving the problems of the existing technology that false negative results, ultra-limit concentration and sensor poisoning often occur in a gas detector used in fire fighting forces. The wide-concentration multi-component hazardous gas detector includes a gas diluting and sampling connector, a sensor integrated module, electrochemical sensors, ADC (analog to digital converter) circuits, MCU (microprogrammed control unit) single chip microcomputers, acousto-optic alarms, a 4-button keyboard module, an LED (light-emitting diode) display module, an SD card data memory module, a power supply control and electric quantity display module, a high-performance lithium battery pack, a small evacuation pump, 433M signal transmission modules and a remote command platform signal collection terminal.
