Czujnik lambda De Dietrich 7632369

The lambda sensor, also known as an oxygen sensor, plays a key role in regulating the air-to-fuel ratio in gas burners. By measuring the oxygen content in exhaust gases, it helps the control unit adjust combustion for maximum efficiency and low emissions. This component is vital for modern heating systems that require precise fuel metering. If your boiler or burner is showing signs of inefficient operation or increased emissions, checking the lambda sensor should be a priority.
