OXYGUARD Dissolved Oxygen Measuring Instrument Unit

Feature & Principle

It adopts galvanic cell principle. Oxygen permeates the membrane and triggers internal chemical reaction to generate electrical signal proportional to oxygen partial pressure, built-in temperature compensation. The signal is converted to standard analog or digital signal and sent to PLC or controller for oxygen monitoring and aeration interlock control.
