What is Nexisense GTYQ-MIC-500S-O2 Fixed Oxygen Detector ?
Nexisense GTYQ-MIC-500S-O2 Fixed Oxygen Detector is a precision-engineered device designed to monitor oxygenconcentration in hazardous environments such as industrial zones, chemical plants, power stations, and mining sites. It utilizes advanced electrochemical sensing technology to ensureaccurate, real-time detection and prompt alarming upon oxygen level deviations, ensuring workplace safety.
Working Principle
The device operates on the electrochemical sensing principle. As oxygen molecules pass through the electrochemical sensor, a chemical reaction occurs with the electrolyte,generating a current signal proportional to the oxygen concentration. This signal is converted into readable data for display and control.
Optional sensing methods such as optical fluorescence and zirconia arealso available for enhanced application flexibility, delivering high stability and accuracy for continuous monitoring.
