The AE8 oxygen analyser has been designed to measure the absolute oxygen content of flue gases or other gas mixtures in industrial applications.
The absolute content of residual oxygen in gases produced during combustion or chemical processes is one of the most important indicators for combustion control. By determining the residual oxygen content, optimum thermal efficiency can be achieved, and negative environmental impact can be reduced.

The basic measuring element of the instrument is a ZrO2 solid electrolyte sensor located directly in the flow of the flue gas to be analysed. Probes for gas temperatures up to 600 degrees Celsius have a ceramic sensor housing equipped with a heating element; high-temperature probes are heated to operating temperature by the directly measured gases. A stainless steel cover provides both protection and support. This is passed through the wall of the boiler and connected to it by the mounting flange.
Cables connect the probe to the instrument housing, which contains the control electronics and all the other equipment necessary for the instrument's operation. At the bottom of the housing, there is a reference air filter, grommets for connecting the probe, power supply and communication signals, and the calibration gas inlet. Calibration can be performed at up to four points (air + 3 calibration gases) without disassembling the analyser.
The AE8 Series analysers can be upgraded with an automatic calibration unit or supplied with a probe design, depending on the specific application.
