    Series 900 – Fixed Indoor Air Quality Monitor

Indoor air monitors

Our indoor air quality monitors are designed to make indoor air quality monitoring easy. They are used by researchers, professionals, and non-experts alike to gather indoor air quality data from indoor environments such as offices, warehouses, public buildings, manufacturing facilities, schools and hospitals, and transport terminals.

Measure multiple indoor air pollutants

The fixed monitors are compatible with a range of gas sensor heads. Each sensor head measures one gaseous pollutant, so sensor heads can be swapped to allow the measurement of the gaseous pollutants you need to measure. Swapping sensor heads is easy – it can be done in the field, with no recalibration required before or after.

The monitors are able to measure common indoor air quality parameters such as: ozone, carbon monoxide, carbon dioxide, volatile organic compounds (VOCs), formaldehyde, and temperature and humidity. For a full list of compatible sensors please check the individual product listing.

Precise measurement at a reasonable price

The monitors were developed with precise measurement (not just detection) in mind. The performance of some sensors is in the ppb range, which is the sort of performance you’d expect from an analyzer worth several thousands of dollars. Instead, these air monitors cost a fraction of that to own and are far less complicated to operate.

Choose the one that’s right for you

For a cost effective feature packed monitor for measuring indoor ozone levels consider the SM70. For an extremely flexible fixed monitor system with multiple outputs available try the Series 900 monitor. For a water and dustproof option consider the Series 930.
