Q22 Portable O2 / CO2 Analyzer
NEXT GENERATION TECHNOLOGY
Introducing the Q22, 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 Q22 incorporates the latest fast response O2 and CO2 sensors, 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
Our standard sample probe assembly for food package testing connects to the Model Q22 – 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
Navigate the user-friendly interface, and 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 Q22 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.
