In-situ oxygen measurement
Fields of application
Ideal for combustion control in boilers, incinerators and furnaces.
Features
The probe 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.
