Wöhler A 550 Flue Gas Analyzer Kit | O₂ CO Combustion Analysis | DM 602 + TD 100 Printer

Used. Excellent working condition.

The Wöhler A 550 Gas Analysis Kit is a professional combustion and flue gas analysis system designed for heating engineers, service technicians, and inspection authorities. This complete set includes the Wöhler A 550 gas analyzer, the Wöhler DM 602 differential pressure meter, and the Wöhler TD 100 thermal printer, providing a full solution for measurement, documentation, and reporting.

Based on the provided images, the Wöhler A 550 is configured for solid fuel and pellet systems (Pellets mode visible) and performs real-time combustion analysis with a large color touchscreen interface. The instrument supports efficiency calculations, draft measurement, temperature analysis, and emissions evaluation in accordance with European regulations (including BImSchV).

All components are supplied in a protective transport case, suitable for field service and mobile inspections.
