JH-BD-4 portable gas detector is an instrument used to detect flammable, explosive, toxic and harmful gases. When the concentration of the measured gas reaches the alarm point set by the instrument, the instrument will emit sound, light and vibration alarms to warn on-site personnel to take relevant measures according to the actual detection situation
