O2controller

Manufacturer: GermanyOFS

General Function Introduction

The oxygen content in boiler hot water needs to be continuously monitoredO2The controller can achieve this function. Through a quickO2Sensors can measure from0.001mg-Saturated oxygen content.

be careful:
The hot water sample must be cooled before entering the equipment. As shown in the above figure.The sample cooler is not included in the supply scope, but can be selected at will
