Providing quick readings wherever there is occupant distress
With its high contribution to Sick Building Syndrome ( SBS) , carbon dioxide concentration is frequently used to evaluate indoor air quality and ventilation. The reliable 535 Carbon Dioxide Monitor can be used to quickly and accurately assess carbon dioxide concentration levels on both a short-term and long-term basis. Easy to use and lightweight, the 535 monitor is completely portable. Its simple keypad makes it easy to operate in any setting. No user calibration is needed due to the monitor’ s highly stable sensor. An optional protective case, wall mounting holder, and carrying holder are all available separately.

Carbon Dioxide & IAQ
Elevated CO2 levels can cause occupants to complain of room stuffiness or a stale air smell. This means there is inadequate ventilation. Improper ventilation also promotes the build-up of other chemical and biological contaminants that can cause health effects in occupants. A method for evaluating IAQ is continuous CO2 monitoring using a datalogging instrument. Supplement CO2 monitoring with measurements of temperature, relative humidity, airflow movement, and airflow volume. For more information on products to sample these parameters, see the Indoor Environmental Quality Instruments page.
