BQG-2118 Zirconia Oxygen Analyzer
BQG2118 zirconia oxygen analyzer is practical and reliable online automatic oxygen analyzer. Its measurement and display
system consists of an oxygen detector (sensor) and a display instrument (transmitter). The detector is made of heatresisting
and anticorrosion materials and can be directly inserted into flues for measurement of oxygen. The display instrument adopts
singlechip control and can be used in combination with various electric unit combination instrument, main display recorder
instruments and distributed control systems (DCS).
Zirconia oxygen analyzer is used for rapid and accurate online measurement and analysis of the oxygen contents in the flue
gas produced by combustion equipments, such as boilers, furnaces and heaters, so as to realize control of lowoxygen combustion,
energy saving and pollution treatment.
Features
The sensor is made of heat-resisting and anti-corrosion materials with high reliability. |
With a special structural design, this analyzer doesn’t need external air pump, and the reference air can realize |
convection by itself. |
The sensor has a standard air interface, which enables calibration check on the site and provides convenient |
maintenance. |
It adopts single-chip control and data processing with quick response, accurate measurement and stable |
performance. |
