Specifications

This analyser is used for continuous measurement of oxygen concentration in flue gases from boilers and industrial furnaces, for combustion control and optimization. It consists of a measurement probe combined with a signal converter. The probe is associated with a convection tube which is inserted into the flue gas to channel the gases to the probe for oxygen measurement. The converter (ZKM) is a microprocessor-based signal converter that manages inputs/outputs, digital communication, display and control of the overall operation. The converter features advanced functions such as self-diagnosis of operation and probe regeneration, giving it very long stability.
