Percent Oxygen Analyzer (GNL-B1F)
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.
