BROTIE Trace O2 Gas Analyzer

Features                                                                                                   

*  imported fuel cell 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 into the air for long time during out of the power or cutting off the gas-route automatically.

*  Setting Upper and lower alarm values freely during the measure ranges.

*  4-20mA signal output

*  One standard RS232C or RS485 interface
