CO2 SENSOR – BASICS
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.
