Model 902D O2 / CO2 Headspace Analyzer

Model 902D O2 / CO2 Headspace Analyzer

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.

ABOUT THE SENSORS

The solid-state infrared CO2 sensor has no moving parts, a compact optical cell, and microprocessor-based calibration factors using a 6th order polynomial equation and 32 bit processor to linearize the full range measurement up to 100%.

Both sensors are unaffected by high levels of background gases such as nitrogen.

The expected life of the CO2 sensor is theoretically unlimited, as it contains no moving parts.

The expected electrochemical O2 sensor life is typically 5 years, unlike other analyzers with an electrochemical sensor that last 1-2 years.

ABOUT THE PUMP

The rugged miniature diaphragm pump has electronically controlled timing function to operate only when sampling.  It provides high flow rate and long operating life.

The pump is electronically timed to draw in the amount of sample required for the analysis, and then turns itself off after the pre-set sampling time (5 to 10 seconds).
