Air QualitySmart Temp SMT-IAQ3 Indoor Air Quality Sensor

Is the air in your building conducive to a healthy work environment? Poor air quality in the workspace can lead to health problems such as sneezing, fatigue or lethargy, headaches and nausea, irritability and forgetfulness. The main factor in air quality in offices is the design, operation and maintenance of the HVAC system.

Introducing the SmartTemp SMT-IAQ3 Indoor Air Quality Sensor

Introducing fresh air into the environment in high enough quantities to keep indoor air quality fresh. However, doing this without some sort of control may lead to excessive heating and cooling running costs as well as undesirable humidity levels.

Carbon dioxide is a recognised indicator of indoor air quality. By monitoring carbon dioxide levels and introducing fresh air only when necessary, assists in keeping the environment healthy.

The SMT-IAQ3 Indoor Air Quality Sensor from Smart Temp monitors carbon dioxide, temperature and humidity. It has a high quality and accurate non- dispersive infrared sensor that constantly measures the level of carbon dioxide in the environment.

When the carbon dioxide level begins to increase, the SMT-IAQ3 will begin to initiate corrective action when connected to a fresh air system and if necessary, warn building occupants using a fitted visual and audible alarm. A pin protected installer menu allows adjustment of alarm thresholds as well as how it will manage the building ventilation systems.

Ventilation Systems

Ventilation systems in large buildings are designed and operated not only to heat and cool the air, but also to draw in and circulate outdoor air. However poor design, maintenance or operation can contribute to indoor air problems. For example, in an attempt to save on energy costs, insufficient fresh air is drawn in.

Inadequate ventilation also occurs if the air supply and return vents within each room are blocked or placed in such a way that outdoor air does not actually reach the breathing zone of building occupants.

Use of the Building

Buildings originally designed for one purpose may end up being converted to use as office space. If not properly modified during building renovations, the room partitions and ventilation system can contribute to indoor air quality problems by restricting air re-circulation or by providing an inadequate supply of outdoor air. Poor ventilation and over population can lead to a build-up of toxins in the air which can contribute to employee health problems.
