Q31 Benchtop CO2 Analyzer
NEXT GENERATION TECHNOLOGY
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.
