Air Quality Sensors & Transmitters

We offer a wide range of air quality HVAC sensors to monitor Volatile Organic Compound (VOC) emissions, Particulate Matter, Carbon Dioxide, Temperature and Humidity. If you are in need of a high-quality sensor for room (IP30), duct (IP65), or outside air (IP65) applications, we have what you need.

Today’s global situation has highlighted the importance of monitoring the indoor air quality (IAQ) in our working/learning environments to keep us comfortable and safe. Historically air quality has been equated to measuring carbon dioxide, humidity, and temperature levels, but there is additional importance in monitoring Particulate Matter (PM) and Volatile Organic Compounds (VOC’s) levels to provide a true picture of the complete indoor air quality. Greystone’s indoor air quality line of products utilizes the latest technologies to provide highly accurate sensing solutions with long-term reliability.

Greystone’s indoor air quality line of products utilizes the latest technologies to provide highly accurate sensing solutions with long-term reliability. Our indoor air quality line of products includes several multi-sensing devices that incorporate two or three sensing capabilities in one product for more efficient installation. All our products are available with a variety of output signal types for connection to a building automation system (BMS) that includes Analog, BACnet® or Modbus communications.

Particulate Matter Sensing

Particulate Matter Sensing

Greystone’s Particulate Matter (PM) sensor uses an optical sensor based on the laser scattering principle and features innovative contamination resistance technology to perform the most accurate and reliable PM measurements of 1.0, 2.5, 4.0 or 10.0 micron particle sizes. With a continuous operation lifetime of more than 8 years, the field-replaceable sensor will provide long-term reliability with high-resolution particle size binning for the detection of environmental dust and other similar particles.

Air Quality Solutions for All Sizes of Office Buildings & Businesses

VOC Sensing

Greystone’s indoor air quality monitoring devices use an advanced MEMS metal oxide semiconductor sensor to detect poor air quality. The sensor reacts quickly to detect a broad range of volatile organic compounds (VOC’s) such as smoke, cooking odors, bio-effluence, building outgases, outdoor pollutants and those from human activities. The sensor captures all VOC emissions that are completely invisible to CO2 and other sensor types.
