The Quantek Model 902D is a benchtop oxygen and CO2 headspace analyzer, primarily used for gas flushed food packages. Achieve accurate oxygen and carbon dioxide measurements in 20-25 seconds. This headspace analyzer contains an internal pump to draw in sample from your package and display O2 and CO2 concentration results in 30 seconds. The expected oxygen sensor life is typically 5 years, unlike other analyzers with a sensor that last 1-2 years, reducing total cost of ownership, and analyzer downtime.
