Abstract
Infrared gas detection system comprising a gas inlet, an infrared gas analyzer connected to the gas inlet and a secondary gas sensor connected to the gas inlet, and an evaluation device evaluating the measurement signals from both the infrared gas analyzer and from the secondary gas sensor, such that a gas is identified only if both the infrared measurement signal and the secondary measurement signal coincide in time.
