K-1-gas

 		 The Nova 314 Portable Oxygen Analyzer is designed to measure the oxygen concentration of a clean, dry sample gas. In operation, a built-in sample pump draws the sample gas into the analyzer and through the sample conditioning filters, flow meter and O2 sensor. An external gas scrubber is available to remove any corrosive gases prior to entering the analyzer, if required.

The zirconia sensor is mounted in a flow-through block through which the sample gas flows. The sensor produces a non-linear µA output proportional to the oxygen concentration. This non linear signal is then linearized and amplified by an O2 processor board. The output is then directed to a main amplifier board which then connects to the digital readout meter and optional recorder output terminals.

Applications  
For continuous high accuracy analysis from PPM to 96% Oxygen (O2) in process gas streams. Other applications include combustion air O2 enrichment, flue gas analysis, O2 deficiency analysis, and many more. Note: Sample gas must not contain combustible gases or vapors.


 

Features  
  • High accuracy, long-life zirconia O2 sensor
  • Rugged design that is easy to operate
  • Fast warm-up and response
  • Digital readout meter with backlight
  • Modular layout that is easy to maintain
  • Rechargeable battery operation
  • Built-in sample pump, filter, and flow meter
  • Bench Top cabinet with front-mounted controls and displays



 

Options  
  • Recorder output of 0-1 V or 4-20 mA
  • Sample pre-cooler for hot samples
  • Condensate removal for wet sample gas
  • Suitcase (K) style cabinet available
  • AC power only operation
  • Low flow and O2 alarms
  • Detachable/portable datalogger



 

Calibration  
  • Analyzed calibration gas of O2-free nitrogen (N2) for zero
  • Air @ 20.9% O2 or analyzed calibration gas of O2 in N2 for span



 

Unique Applications  
The 314 series analyzers should not be used on sample gases containing flammable gases. These gases will be burned by the zirconia sensor along with any available O2 and cause the analyzer to display readings that are lower than the actual values.

All Nova analyzers are built using proven technologies and techniques. If this product does not suit your application, please contact Nova. In many cases, we are able to build an analyzer specific to your needs.
