BROTIE Portable Trace Oxygen Purity Analysis Meter for Laboratory

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)
