Household gas detector SGB 1-2B

The SGB-1-2B alarms are designed to monitor gas contamination in communal and domestic premises, furnace rooms and low-power boiler houses.
The SGB-1-2B alarm provides light and sound signaling when the concentration threshold is reached, as well as switching external AC and DC electrical circuits and controlling the pulse shut-off valve.
Main technical characteristics:
Controlled components: Methane, Carbon monoxide
Nominal value of signal concentration:
Methane - 0.1%
Carbon monoxide - 0.01%

Limit of permissible basic absolute error when triggering an alarm under actual operating conditions, %:
+ 0.035 (for methane)
+ 0.0035 (for carbon monoxide)

The alarm response time is no more than 60 sec.
The alarm warm-up time is no more than 5 minutes.
The sound pressure level when emitting a signal along the axis of the sound emitter at a distance of 1 m is not less than 60 dB.
