Carbon monoxide (CO) is a dangerous gas because it is colorless and odorless, making it undetectable to humans. CO detectors are required when using, for example, fireplaces, gas stoves, gas water heaters, oil-fired stoves, wood-burning stoves, or tiled stoves. We recommend installing one CO detector per bedroom. This life-saving device is tested in accordance with the strict, current EN 50291:2001 standard. https://elecena.pl/product/18544474/20566-co-gas-detector-with-figaro-sensor-and-display 2021-05-22 https://elecena.pl/product/18544474/20566-co-gas-detector-with-figaro-sensor-and-display 2022-05-17 https://elecena.pl/product/18544474/20566-co-gas-detector-with-figaro-sensor-and-display 2023-04-06 https://elecena.pl/product/18544474/20566-co-gas-detector-with-figaro-sensor-and-display 2025-01-23 https://elecena.pl/product/18544474/20566-co-gas-detector-with-figaro-sensor-and-display 2026-09-11 https://elecena.pl/product/18544474/20566-co-gas-detector-with-figaro-sensor-and-display 2026-10-23 https://elecena.pl/product/18544474/20566-co-gas-detector-with-figaro-sensor-and-display 2026-10-28
