The Q3 is a portable CO2 analyzer, used for incubator and other process testing.   Simply insert the sample probe into the sampling port on your incubator, press the pump button, and
obtain results quickly and accurately.    The Q3 weighs only 2 lbs, and comes with rechargeable batteries, sample probe, charger, and  accessories to begin sampling. There is also a hard carry case for easy portability and protection.    The Model Q3 is designed for spot check monitoring of CO
2 levels in all types of incubators,  processes, gas blending, biotech, and other systems. It is available with measurement of ranges 0-
20% or 0-100%. Battery operation and carry case are included


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


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 and is unaffected by other gases.


The Model Q3 is backed up with a two year warranty, twice the industry standard.
