The Q2 is a portable headspace analyzer for measurement of O2 and CO2 levels in gas flushed MAP packages (such as coffee or meat products).  Alternately, the Q2 can be used for portable O2 and CO2 measurements for research applications (such as cell culture incubators).

It weighs only 2 lbs, and comes with rechargeable batteries, sample probe, charger, and accessories to begin sampling.  There is also an optional hard carry case for easy portability and protection.

ULTRA FAST

The Model Q2 incorporates the latest fast response O2 and CO2 sensors, which allows results to be obtained in 15 seconds for rapid spot checks.  The oxygen sensor is also rated for 5 years of life, which is far better than the competition.   Other analyzers utilize cheap oxygen sensors which may last 18-24 months.

EASY SAMPLING METHOD
Our standard sample probe assembly for food package testing connects to the Model Q2 – this sample probe is interchangeable with all of our other analyzers, and is a durable double tubed, single piece.

The probe is tipped with a liquid blocking filter and tri-beveled, non coring needle.    The filter will block liquid and particle intake into the analyzer, and the needle is specially designed to prevent “coring”, or plugging, and is incredibly tough.

USER FRIENDLY, ACCESSIBLE CONTROLS

On the side of the instrument there are five adjusting potentiometers – you can adjust the oxygen span, pump time, CO2 span, and other parameters on the fly.  There’s no need to reboot and no need to warmup – it’s as easy as it gets.

ABOUT THE SENSORS

The infrared CO2 sensor utilizes NDIR technology for maximum stability, and has a theoretically unlimited lifespan.  Its ultra low power consumption allows for 10-14 hours of runtime for the analyzer before recharging is required.

It has no moving parts, no consumables, and is housed in a compact optical cell. The sensor responds to CO2 only.

The electrochemical O2 sensor life is typically 4-5 years, unlike other analyzers with an electrochemical sensor that last 1-2 years. When required, replacement is easy and inexpensive.

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

WARRANTY STATEMENT

The Model Q2 is backed  up with a two year warranty, twice the industry standard.

The Quantek Model 901 is a battery-operated, portable headspace oxygen analyzer.

Other headspace analyzers require a new sensor every 1-2 years.   But our flagship headspace oxygen analyzer, which is used by small and large food packagers, producers, and quality control personnel throughout the world.

Use it in the lab, or on the packaging line.  Non-technical personnel will find it very easy to use – and at less than 3 pounds, it can be easily transported to other locations.

HOW TO SAMPLE YOUR PACKAGES

The sample probe is tipped with a filter and needle.  Simply affix the foam septa to your package, insert the needle through the septa, and press the pump button.  Sample is drawn through the probe and into the internal oxygen sensor.    The residual oxygen concentration displays within 15-20 seconds.

LOWEST TOTAL COST OF OWNERSHIP

The Model 901 oxygen analyzer is the market leader for durability, simplicity, and reliability.  The initial lower cost, and longer-life sensor, makes it the industry leader in handheld portable headspace oxygen analyzers.

ABOUT THE INTERNAL OXYGEN SENSOR

The sensor is unaffected by high levels of background gases such as nitrogen or carbon dioxide, and unaffected by trace hydrocarbons.  You can use the Model 901 for applications where oxygen level is very high (50 to 100%) without overloading the sensor.  The expected electrochemical sensor life is typically 5 years, unlike other analyzers with an electrochemical sensor that last 1-2 years.

LIQUID BLOCKING FILTERS

Sample with confidence using our liquid blocking filters – all contamination is blocked from entering the analyser, reducing downtime significantly.

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. This O2 CO2 Analyzer contains an internal pump to draw in sample from your package and display results in 30 seconds. 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. 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). OPTIONAL RECHARGEABLE BATTERY Totally sealed, long-life gel 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. MICROPROCESSOR/ELECTRONICS Micro-processor based electronics provide sensor signal processing, battery charging, pump timing and on/off control for high accuracy and reliability with minimal component use and reduced size and cost.

Applications:

 – Coffee producers use our Model 902D to test residual O2 and CO2 levels in coffee packages.

 – Chicken producers use our Model 902D to test the oxygen and carbon dioxide levels in packaged chicken.

 – Fresh Produce packagers use our Models 901 and 902D to check the effectiveness of their gas flush process.

 – Pet Food producers use our Model 902D and Model 901 to measure residual O2 and CO2 levels in pet food packages.

 – Mushroom producers use our Model 901 oxygen analyser to check the oxygen levels in their mushroom containers.

 – Cheese producers especially shredded cheese producers use our Model 902D to check oxygen and carbon dioxide content after packaging.

– Gourmet Dessert Manufacturers: Nitrogen flushed packages of sweets are checked with a Model 901 to preserve freshness of product and measure residual oxygen.

 – Wine Products: Wineries use our Model 901 to measure residual oxygen in flexible packaged wine products.

The Model 905 is used primarily for the measurement of residual oxygen in CAP/MAP food packages.  With an expected oxygen sensor life of 4-5 years, it vastly outperforms other oxygen analyzers with a cheap sensor that might last 1-2 years.

Use it in the lab, or on the packaging line.   While the performance and functionality is the same as our Model 901, the Model 905 is the better choice for conducting testing when the operator is stationary.  This is primarily due to its tip up feet, and form factor.   Also, its high end rugged metal enclosure ensures its overall durability.

HOW TO SAMPLE YOUR PACKAGES

The sample probe is tipped with a particulate filter and syringe needle.  Affix the foam septa to your package, insert the needle through the septa, and press the pump button.  Sample from your package is drawn through the probe and into the internal oxygen sensor.

The pump will draw about 5 cc/second from your package.  The pump will run from 2 to 12 seconds and this time is easily adjustable using the controls.  This adjustment is especially important for packages of varying size, or for rigid packages.  The oxygen measurement displays on the LCD within 15-20 seconds.
