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 analyzer, reducing downtime significantly.

Introducing the Q20, the next generation of Quantek analyzers. This analyzer utilizes the latest in microprocessor-based sampling, and comes equipped with an advanced TFT display, smart charging, onboard data collection, advanced pump functions, and EasyCal calibration controls.

LONG LIFE, STABLE SENSORS

The Model Q20 incorporates the latest fast response O2 sensor, which allows results to be obtained in 15-25 seconds for rapid spot checks. The oxygen sensor is 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

The sample probe connects to a barbed inlet fitting that is attached to the analyzer.  Extra probe tubing is included with each analyzer for easy exchange in case of contamination or damage.  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 plugging.

USER FRIENDLY, ACCESSIBLE CONTROLS

Navigate the user-friendly interface, and you can adjust the oxygen span, pump time, and other parameters on the fly.  There’s no need to reboot and no need to warmup – it’s as easy as it gets.

EASY SAMPLING METHOD

The Q40 series sample inlet and outlet are located on the rear panel for ease of access.  By default, both fittings are 1/8” stainless steel Swagelok.  Other inlet/outlet configurations are available upon request.  Some examples include standard luer fittings, ¼” Swagelok fittings, or a sample probe.  We can recommend or customize fittings to give the most seamless sampling experience for whatever system you may have.

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.

LOWEST TOTAL COST OF OWNERSHIP

The Model 905 oxygen analyzer is the market leader for durability, simplicity, and reliability. The initial lower cost, and longer-life sensor, makes it best in class for laboratory package 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 905 for applications where oxygen level is very high (50 to 100%) without overloading the sensor. The expected oxygen sensor life is typically 4-5 years, unlike other analyzers with a sensor that last 1-2 years.

The Model 905V is a rugged benchtop unit housed in a heavy-duty metal enclosure, well suited for continuous use in routine QC testing in the laboratory. With built-in battery operation (optional) in addition to the AC mode, this unit can be easily transported and used at remote locations such as the packaging line.

Model 905V Key Features and Attributes

ABOUT THE SENSOR

The Model 905V sensor is designed specifically for this purpose. The oxygen sensor internal chamber has a very small volume of about 0.1 cc. The sensor is located directly behind the front panel to eliminate excessive volume. The sensor has in /out ports with a 0.03 in. ID. The vent port of the sensor connects to a short piece of narrow-bore tubing for sample exhaust and introduction of zero or calibration gases.

CALIBRATION SIMPLICITY

The oxygen sensor output is very linear through the entire range of measurement. This allows for a single point calibration to be performed anywhere in the measurement range. Span calibration is accurately done by testing room air, which should give a reading of 20.9% oxygen. Calibration standards can also be used if required by in-house test procedures.

DESIGN RELIABILITY

Microprocessor based electronics are used for sensor signal processing, battery charging and on/off control to provide high accuracy and reliability. The heavy duty, proprietary oxygen sensor is designed to provide many years of service, is totally sealed and requires no maintenance. The sensor output is compensated for ambient temperature variations.

ABOUT THE OPTIONAL BATTERY

With its low power requirement, the Model 905V can be operated with an optional battery for those applications where AC power is not readily available, or for convenience if spot checking samples at different locations. A totally sealed, long-life internal 12 Vdc gel battery accepts a full or partial charging cycle and will operate the unit for up to 8 hours. The charger module plugs into a standard 110-240V outlet for charging or continuous operation. Alternatively, the unit can be powered from an external 12-24 Vdc source.

The sensor is a proprietary electrochemical type with a measurement range of 0.0 to 100%. Excellent linearity through the entire range allows a calibration with one set point using room air. It is unaffected by high levels of background gases such as nitrogen or carbon dioxide. The Model 201 can be used for applications where the oxygen level is very high (50 to 100%), without overloading the sensor. It is unaffected by trace hydrocarbons or high levels of CO2, which can poison other types of sensors, and operates independent of flow rate.

BATTERY OR AC OPERATION

The Model 201 comes in two configurations – pick either AA battery operation, or AC power operation to allow for 100% uptime.

The sensor in the Model ZR1000 is a robust, heated zirconia element with typical lifetime of 5 years, with an excellent response to trace O2 levels down to single numbers, in all types of inert gas environments. The inlet and outlet are isolated from ambient air by double check valves on both sides, protecting the sensor from high O2 levels when not in use.

Unlike electrochemical ppm oxygen sensors, the ZR1000 sensor will not degrade when the instrument is powered off, and exposed to room air. This eliminates the need to flush the instrument with a gas such as nitrogen, and keep the instrument completely sealed from the environment.

Electrochemical ppm sensors can have a lifespan as short as 3 months, which requires constantly purchasing and installing new sensors. Even worse, if the replacement sensor is not stored properly, you may end up with a sensor that has already degraded. Our zirconia sensor eliminates these problems entirely.
