Portable trace oxygen analyzer

Portable trace oxygen analyzerPrinciple and Construction

Portable trace oxygen analyzerUsing the detection principles of electrochemical primary cells/electrochemical fuel cells to analyze the oxygen content in various background gases, the core detection components areTwo GOC series oxygen sensors (GALVANIC OXYGEN CELL).It can detect the oxygen content in various background gases, such as nitrogen, hydrogen, argon, argon, helium, methane, as well as gases containing VOCs, organic solvents, slightly acidic gases (H2S, CO2, etc.), and hydrocarbons.

This portable trace oxygen analyzerEncapsulated in a sturdy all-weather weather resistant casing. It is powered by rechargeable batteries and can be used continuously for up to 15 hours. Use flow control valves and flow meters to control and monitor the sample gas passing through the analyzer. In the case of insufficient gas source pressure, an optional vacuum pump can be selected.

This portable trace oxygen analyzerUse two GOC series oxygen sensors: a constant oxygen sensor and a trace oxygen sensor. When starting the machine in the air, the constant oxygen sensor is in the detection state. When the constant oxygen sensor detects that the oxygen content in the sample gas is below 5000ppm, 2000ppm, or 1000ppm, it will emit an LED alarm. At this time, the instrument willautomaticor needmanualSwitch to using a trace oxygen sensor to accurately detect the oxygen content in the sample gas and display the detected readings in real time.

this modelPortable trace oxygen analyzerThis dual sensor design can effectively prevent the micro oxygen sensor from coming into contact with high oxygen atmospheres such as air, thereby extending the lifespan of the micro oxygen sensor and greatly accelerating the response time of the instrument.
