Introducing the Q31, 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 Q31 incorporates the latest fast response CO2 sensor, which allows results to be obtained in 15-25 seconds for rapid spot checks.  The CO2 detector is a dual wavelength NDIR sensor with a theoretically unlimited lifespan.

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.  Extra tubing is provided for incubator or other process applications.

USER FRIENDLY, ACCESSIBLE CONTROLS

Navigate the user-friendly interface, and you can adjust the CO2 calibration, 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.

ABOUT THE SENSOR

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 sensor is unaffected by high levels of background gases such as nitrogen or oxygen.

WARRANTY STATEMENT

The Model Q31 is backed up with a two-year warranty, twice the industry standard.
Our service team responds quickly to the repair needs of our customers, and repairs and calibrations are conducted in our advanced facility in Massachusetts.

Introducing the Q41, 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 Q41 incorporates the latest fast response CO2 sensor, which allows results to be obtained in 15-25 seconds for rapid spot checks, or run continuously for process monitoring.  The CO2 detector is a dual wavelength NDIR sensor with a theoretically unlimited lifespan.

EASY SAMPLING METHOD

The Q41 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 sensor design is compact, has a low internal volume and requires a flow rate of > 700 cc/min.  For ppm applications where accuracy is essential, this is the most precise option in the Quantek catalog.

CO2 SENSOR – DETAILS

The Model 906 uses a solid-state infrared sensor which has no moving parts, a compact optical cell, and microprocessor-based calibration factors using a 6th order polynomial equation to linearize the full range measurement up to 2000ppm.   Enhanced temperature and humidity compensation allow for excellent accuracy – typically +/- 10ppm between 100 and 1000ppm, and +/- 5ppm between 0 and 100 ppm.

EASE OF SAMPLING

Sample gas flows into the analyzer through the front panel fitting, and vents out through an exhaust port on the back panel. The exhaust port can also be equipped with a connectible luer fit connection, should you wish to keep your system closed.

The sensor operates at atmospheric pressure, and a flow bypass in the internal plumbing arrangement allows for excess pressure to vent. This allows for higher acceptable flow rates, without affecting the accuracy of your measurements.

DATA COLLECTION OPTIONS

If you have your own data acquisition equipment already, we can equip the Model 906 with a 0-10Vdc or 4-20mA output on the back – linear to the concentration displayed on the LCD.

If you do not have data acquisition equipment, we offer a complete data logging solution. This solution allows you to record readings at intervals from 1 second to 18 hours, and comes complete with graphing/analysis software. The results can then be exported via .csv or .txt files to other software for analysis.

ABOUT THE WARRANTY

The Model 906E is backed it up with a two year warranty, twice the industry standard. The advanced design allows an output requiring less frequent calibration. It provides a stable, drift-free linearized voltage or current output that is much less susceptible to external electro-magnetic interference than conventional analog electronics.

The sensor design is compact, has a low internal volume and requires only a low sample flow of about 5 to 1000 cc/min. Our market leading CO2 sensor uses the latest in dual-wavelength NDIR measurement principles, reducing drift and allowing for results in as little as 10-15 seconds. While the sample introduced should be clean and dry (non-condensing), should moisture enter the analyzer, the Model 906 is equipped with an internal moisture trap filter. This provides a last barrier of protection, and is user-replaceable (we provide spares).

CO2 SENSOR – DETAILS

The Model 906 uses a solid-state infrared sensor which has no moving parts, a compact optical cell, and microprocessor-based calibration factors using a 6th order polynomial equation to linearize the full range measurement up to 100%. Infrared CO2 measurements are inherently non-linear, especially over a high range of concentrations. The math algorithm used in the 906 yields more accurate measurements over a much wider range of concentrations than other methods.

EASE OF SAMPLING

Sample gas flows into the analyzer through the front panel fitting, and vents out through an exhaust port on the back panel. The exhaust port can also be equipped with a connectible luer fit connection, should you wish to keep your system closed.

The sensor operates at atmospheric pressure, and a flow bypass in the internal plumbing arrangement allows for excess pressure to vent. This allows for higher acceptable flow rates, without affecting the accuracy of your measurements.

DATA COLLECTION OPTIONS

If you have your own data acquisition equipment already, we can equip the Model 906 with a Vdc or 4-20mA output on the back – linear to the concentration displayed on the LCD.

If you do not have data acquisition equipment, we offer a complete data logging solution. This solution allows you to record readings at intervals from 1 second to 18 hours, and comes complete with graphing/analysis software. The results can then be exported via .csv or .txt files to other software for analysis.

ABOUT THE OPTIONAL BATTERY

With its low power requirement, the Model 906 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 battery accepts a full or partial charging cycle and will operate the unit for up to 8 hours. The charger module plugs into any international 100-240V outlet, for charging or continuous operation. The analyzer need not be turned off during the charge cycle.
