The Model 902D is a bench top oxygen and CO2 headspace analyzer, primarily used for gas flushed food packages.

The Model 902D is a battery-operated, portable oxygen analyzer used for the measurement of residual oxygen in gas-flushed (CAP/MAP) food packages
MODEL 902D TABLE TOP OXYGEN HEAD SPACE & CO2 ANALYZER
The 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.

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.
        Applications

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.
EASY SAMPLING & ANALYSIS
The Model 902D analyzer sample probe is tipped with a particulate filter and luer fit syringe needle with side-port holes to prevent plugging. When the pump is activated, sample is drawn through the probe and tubing and then to the oxygen sensor.

The pump is electronically timed to draw in the precise amount of sample required for the analysis, and then turns itself off after the pre-set sampling time (5 to 10 seconds). The O2 and CO2 concentration is read on the display within 20-25 seconds.

What's Included
Includes everything you need to begin sampling:
• Built-in pump, sample probe.
• Starter pack of 200 foam septas
• 2 needles.
• 2 particulate filters,
• 2 moisture blocking filters
• Power supply / charger - (International compatible 100-240V)
Optional Items
• OPTIONAL RECHARGEABLE BATTERY - Totally sealed, long-life battery (optional) accepts full or partial charging cycle. 
Charger module plugs into standard 115V outlet for charging or
continuous operation, though it can accept 100-240V for worldwide use.

• SUPER FAST SENSOR - For high volume sampling, upgrade to our super fast sensor for results
in 5 seconds (normal test results in 15 seconds)

• .01% RESOLUTION - Upgrade to optional .01% LCD resolution (normal resolution 0.1%)

• LIMITED HEADSPACE MODIFICATION 
This analyzer can be modified for some limited headspace applications, such as for testing vials and bottles. For customers with extremely limited headspace, the use of our Model 905V is required. Please inquire for more details + specifications
- and ask about the "Model 905LV", which is not listed as a separate product on the website.

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).
