General Introduction

Yokogawa AV550G multi channel zirconia oxygen analyzer averaging converter for multiple point oxygen measurement system, required for situations when gas stratification in the flue duct affects combustion control. It accept inputs from up to eight zirconia oxygen detectors. It sends output signals for the individual as well as averages of multiple oxygen concentrations. A robust multipoint converter reduces installation and maintenance costs.
