It is a difficult balance to save money and energy yet maintain a comfortable and healthy indoor air environment. A logical solution to controlling indoor air pollution is good ventilation coupled with IAQ monitoring using gas sensors. This can ensure healthy indoor air as well as a more efficient HVAC system.
Typical IAQ investigation and examination consists of taking single-point measurements of pollutant levels. This monitoring method is unreliable, as the pollutant levels are subject to hourly, daily, and seasonal fluctuations.
PPM Technology has developed a range ofc ontinuous monitoring instruments for IAQ; continuous monitoring means the problems associated with single-point measurements are eliminated; the system is able to monitor multiple IAQ parameters continuously in real time.
