Yokogawa AV550G-B-A6-1O2

Digital guide

Product Overview

AV550G series is a dedicated high-end averaging converter developed by Yokogawa for industrial flue gas oxygen detection and combustion optimization. It matches perfectly with zirconia oxygen detectors, realizes multi-point oxygen signal collection, centralized calculation and average value output, and is widely used in boiler flue gas analysis, industrial furnace combustion efficiency optimization and flue gas emission monitoring scenarios. The two models differ in channel configuration for on-site multi-point layout selection.
