What is proposed is a gas analyzer module (1) for analyzing a measurement gas (7), comprising: - an opto-pneumatic detection system (11) which is designed for detecting an infrared radiation (2) which is radiating through the measurement gas (7), wherein the opto-pneumatic detection system (2) comprises a pressure or flow sensitive sensor (14), and wherein the opto-pneumatic detection system (11) is designed for generating a measuring signal, - a compensation system (6, 13a, 13b) which is designed for generating a compensation signal to compensate disturbing effects which comprises a further pressure or flow sensitive sensor, - an analysis system (20) which is designed for creating a measuring result out of a difference between the measuring signal and the compensation signal, and - a reflecting system (15, 16) which is designed for reflecting the infrared radiation (2), which has been radiated through the opto-pneumatic detection system (11), back to the opto-pneumatic detection system (11). The module (1) is characterized in that the reflecting system (15, 16) comprises: - a reflection plate (17) which comprises a rough surface which is designed for reflecting diffusely the infrared radiation (2) which radiates on the reflection plate (17) back to the opto-pneumatic detection system (11), and - one or more distance elements (18a, 18b, 18c, 18d, 18e, 18f) which are designed for providing a specific distance (19) between the reflection plate (17) and the opto-pneumatic detection system (11) to determine the amount of the infrared radiation (2) which is reflected diffusely back to the opto-pneumatic detection system (11).
