Don Horne   

The ABB AZ40 oxygen and combustibles analyzer continuously samples and analyzes combustion waste gases. It determines the levels of excess oxygen using a zirconia based oxygen sensor and unburnt fuel with an enhanced carbon monoxide detector to measure the carbon monoxide equivalent (COe). By monitoring oxygen and combustible levels in the exhaust gas, it optimizes the air to fuel ratio and reduces soot and slag build up.
