This is an Alfa Laval AAL7000 Oxygen Analyser, an instrument specifically designed for marine applications to monitor oxygen levels in inert gas systems.
- Technology: It utilizes a zirconia-oxide oxygen probe that generates a signal based on the oxygen content present in the sample line.
- Components: The system consists of a monitoring unit with a 2 x 16 character backlit display and four operation keys, paired with the sensing probe.
- Functionality: The “Sensor heating” message on the screen indicates the device is in its initial warm-up phase, as zirconia sensors must reach a specific high temperature to function correctly.
- Applications: It is primarily used on vessels to ensure the safety and efficiency of inert gas generators by providing accurate oxygen concentration readings.
