New Dual Gas Sensor Head, O3, and NO2

AEROQUAL DUAL SENSOR HEAD O3, NO2 (MS3

The Dual Range Sensors from aeroqual can measure two gasses at one time to save you time and money.
The MS3 sensor can measure Ozone (O3) and Nitrogen Dioxide (NO2) simultanously using a fan based sensor for real-time measurement.

This Dual Gas sensor will measure Ozone (O3) and Nitrogen Dioxide (NO2) simultanously and real-time with only one sensor.

The new O3-NO2 dual sensor is designed specifically for outdoor and indoor air quality professionals who wish to measure these two criteria pollutants simultaneously. The dual sensor incorporates a proprietary algorithm which automatically corrects for ozone interference on the electrochemical NO2 sensor, resulting in true real-time measurements of both gases. Aeroqual has filed for a patent on this unique technology which we believe is a world first.

Carbon Dioxide Sensor uses GSE technolgoy to measure NO2 from 0-1 ppm, with a resolution of 0.001 ppm.  Accuracy of 10%, and a minimum detection limit of 0.005 ppm.

Ozone Sensor uses GSE technolgoy to measure O3 from 0-10 ppm, with a resolution of 0.01 ppm.  Accuracy of 7.5%, and a minimum detection limit of 0.01 ppm.

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 currenty 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 dual gas head and react accordingly.
