In-situ oxygen measurement
Fields of application
Ideal for combustion control in boilers, incinerators and furnaces.
Benefits
This analyser is used for the continuous measurement of oxygen concentration in the flue gases of industrial boilers and furnaces to control and optimize combustion. It consists of a measurement probe connected to a signal converter. The probe is connected to a convection tube that is inserted into the flue gases to channel the gases toward the probe for oxygen measurement. The converter (ZKM) is a microprocessor-based signal converter that manages the inputs/outputs, digital communication, display, and operational control of the entire system. The converter features advanced functions such as operational self-diagnosis and probe regeneration, which ensure its long-term stability.
