This IAQ monitor has an auto-zero function and takes measurements with accuracy in a simple design. 

This series of IAQ monitors can measure ambient temperature, relative humidity (rh), wet bulb, dew point, differential pressure, barometric pressure, CO₂, CO, O₂, ozone, formaldehyde, volatile organic compounds, NO, NO₂, SO₂, and H₂S. 

CoorsTek Sensors, a developer of smart sensors across diverse markets including HVAC, announced that it has acquired sensor company Pegasor Oy of Tampere, Finland. Pegasor produces fine and nanoparticle sensor technologies.

Unsafe levels of carbon monoxide, carbon dioxide, and other toxic gases can threaten the health and safety of occupants inside buildings and homes. 

IAQ monitoring and management systems can provide a healthy and productive indoor environment while saving both energy and money, notes Navigant Research. Worldwide revenue from IAQ systems is forecast to grow from $3.3 billion in 2014 to nearly $5.6 billion by 2020.
