Hersch Galvanic Cell Type Trace Oxygen Analyzer MK3 Series
Applications
●Measurement of oxygen concentration of industrial gases
・ Gas purity monitoring and control for Air Separation Unit
・ Gas purity monitoring for product gases
・ Verification of gas purifiers
●Measurement of oxygen concentration of different processes
・ Oxygen monitoring and control for blanketing gases
●Monitoring and control of oxygen concentration for heat treatment furnaces and reactors                                                                                    
Features
●Zero gas/span gas generators built-in
No bottled zero gas/span gas required
●Mass flow controller built-in
By the mass flow controller, no manual flow adjustment required.
Flow is automatically adjusted independent of sample gas pressure fluctuations.
●Four fixed measuring ranges
●Temperature compensation circuit built-in
The built-in temperature sensing element minimizes the influence of ambient temperature on
measurement.
●Automatic distilled water supply (only MK3/NJ)
