Natural gas sensor 230V AC OR-DC-614

A modern alarm device for detecting natural gas concentration indoors. It is used for continuous monitoring of the presence and detection of flammable gases escaping from leaks. The device uses a high-quality semiconductor sensor, which allows to achieve a high rate of detection. An additional relay output enables the impulse to be transferred to another device when the alarm concentration is exceeded (e.g. to a fan, alarm siren, telephone dialer, etc.).
