Gnl-B1a Portable Trace Oxygen Analyzer

GNL-B1A portable trace oxygen analyzer is used to measure the oxygen concentration in clean, dry and noncorrosive gas in plus pressure and widely used in the fields of nitrogen separation from air, petrochemical, metallurgy, electronic power and machinery manufacture.

Features
Advanced electrochemical oxygen sensor, long life, high precision and fast response
Measuring oxygen concentration in H2 or deoxidize gas
Inner special gas-route protects the sensor when it exposures in the air for a long time by out of power or cutting off the gas-route automatically.
Concise menu, simple operation
Automatic temperature compensation, eliminating the impact of environmental temperature.
DC power supply, using neatly. Full charging battery can use continually about 8 hours.
Inner air pump(option)
