GNL-9100 online trace oxygen analyzer is the online intelligent measurement instrument, which adopting advanced fuel cell oxygen sensor with single chip technology.
Features
Imported fuel cell type 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
Automatic data storage in a certain interval time, and browsing data at any time
Big screen DOT-matrix LCD, showing oxygen concentration, date and time synchronously
Setting upper and lower alarm values freely during the measure ranges
It can achieve two-way communication by connected to a computer via the standard RS232 or RS485 interface.
