Carbon Dioxide (CO2) sensor head whose Non-dispersive Infra-red (NDIR) sensor will measure CO2 from 0-2000 ppm with a 1 ppm resolution providing an accuracy of <± 5% of reading.

This head uses an active sensor technology with an internal fan to pull air across the NDIR sensor at a specific flow rate for accurate gas detection. This fan will pull a fresh gas stream across the NDIR sensor every 120 seconds for accurate CO2 detection.

This sensor head will be a direct fit onto any Series-200, Series-300, or Series-500 Aeroqual ozone monitor.  This head can be purchased as an addition to your existing monitor, or with a new base unit.  To purchase with a base unit see our Aeroqual ozone monitor page.  If you currently have an Aeroqual ozone monitor this sensor will be a direct fit for your current monitor.  The Series-200, Series-300, or Series-500 will automatically detect this as a 0-2000 ppm NDIR Carbon Dioxide head and react accordingly.
