Introduction GNL-9100 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.
