The Quantek Model Q21 CO2 Analyzer is designed for spot measurement and analysis of carbon dioxide levels. Analysis ranges of 0-20% or 0-100% vol/vol.
HIGHLY PORTABLE
The Q21 portable analyzer weighs about 2 lbs and is easily carried. Battery operation is included and provides approximately 12 hours of run time.EASE OF USE
The analyzer is equipped with an intuitive set of menus, making operation and calibration fast and easy.CO2 SENSOR – BASICS
The sensor design 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 a single point calibration. While the sample introduced should be clean and dry (non-condensing), a PTFE filter can be attached to the tip of the sample probe to protect from moisture and particulates.CO2 SENSOR – DETAILS
The instrument 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 Q21 yields more accurate measurements over a much wider range of concentrations than other methods.DATA COLLECTION
The Q21 is equipped with onboard data logging – simply export the data to a CSV file to the included thumb drive. You can collect data continuously, at the end of each test automatically, or when you press the “save” button.ABOUT THE BATTERY
The Q21 CO2 analyzer is equipped with an advanced 6 cell NiMH battery pack. The charger module plugs into any international 100-240V outlet, for charging or continuous operation.ABOUT THE WARRANTY
The portable CO2 analyzer 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.
