DHI -HY-GB40A

DHI-HY-GA40A Gas Alarm is designed to continuously monitor methane concentration. Adopting a catalytic-type gas sensor, advanced electrical technology, MCU, a built-in high-volume buzzer, it responds quickly and becomes highly sensitive with stable performance and low false alarm. Once the surrounding methane concentration reaches the alarm threshold, it will promptly send out visual and audible alarm signal to remind the user to take immediate measures. The exhausting fan can be linked to the relay output port to send out combustible gas. The Device can also close the pipeline valve to cut off the gas source.
