JH-BD-4 Portable Gas Detection Alarm Device
The JH-BD-4 portable gas detector is designed to detect flammable, explosive, toxic, and harmful gases. When the measured gas concentration reaches the alarm point set by the instrument, it triggers sound, light, and vibration alarms to warn on-site personnel to take appropriate action based on the detection situation.
