เครื่องวิเคราะห์ออกซิเจนแบบ Portable Trace Oxygen (Global Trace Oxygen Analyzer (GNL-B1)

Introduction
GNL-B1 portable oxygen analyzer is used to measure the oxygen concentration in clean, dry and noncorrosive gas in plus pressure and widely used in the fields of nitrogen separation from air, petrochemical, metallurgy, electronic power and machinery manufacture.

Features
*Advanced electrochemical oxygen sensor, long life, high precision and fast response
*Measuring oxygen concentration in H2 or deoxidize gas
*Inner special protection 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 continue about 12 hours.
*Inner air pump(option)
