Overview

The GNL-3100 series oxygen and nitrogen transmitter is a new intelligent detection instrument that combines the current ion flow sensor with a microcontroller. It has a N2 display (N2%=100-O2%) and is widely used for detecting oxygen content in industrial production processes such as air separation nitrogen production, fertilizers, petrochemicals, and biological fermentation.
