A PC controlled Indoor Air Quality (IAQ) Real Time Monitoring System allowing the networking of several monitoring units, which can all simultaneously measure up to six different IAQ parameters including formaldehyde, carbon dioxide and carbon monoxide. Each individual unit can be set to monitor at regular intervals over a set period of time using a single PC and the data from all the units can be displayed graphically.

The system has been designed to give a visual representation of indoor air quality in buildings, as part of the buildings management standards in relation to conditions such as Sick Building Syndrome. Since a great number of units can be networked, the system can show precise changes in concentration of selected air quality parameters in various locations over time.

The system can be used to profile all the primary and some of the secondary IAQ parameters, and by integrating it with the building's own management system, air quality level signals from the real time monitoring system can be used to control the operation of an air-conditioning system

Using state of the art gas sensing, automatic sampling, data logging, digital technology and information technology, IAQ profiling can be accurate, efficient and therefore cost effective. This system has a dual environmental benefit, firstly by immediate warning of over exposure to harmful toxic gases to the public / workers, and secondly to avoid the waste of energy and resources due to better control of the air conditioning system.
