ABB 856666 oxygen sensor with connector | manufacturer spare part for coal mill gas analysis systems
What is ABB 856666 and where is it used?
ABB 856666 is a manufacturer spare part for ABB gas analyzer systems. Its full name is “Oxygen Sensor with Connector”, and it is mainly used to measure oxygen concentration in coal mill gas analyzers. After long periods of operation the oxygen sensor wears through its electrochemical reaction and loses sensitivity, so regular replacement is necessary to keep measurements accurate.
Besides the 856666 oxygen sensor, JIAHON can also help source other probes and accessories for ABB analyzer systems, including pH electrodes, ORP probes, conductivity sensors and dissolved oxygen sensors. ABB analyzers are widely used in power, petrochemical, water treatment, pharmaceutical and semiconductor processes. Probes are consumable spares replaced on a schedule; keeping them on hand avoids measurement interruptions that affect process quality.
