AQ7 Series - Industrial Gas Sensors

The new AQ7 Series from Honeywell is the innovative gas sensor solution designed for environmental applications with high resolution and long-term stability. The AQ7 Series is equipped with algorithmic compensation to provide highly accurate measurement results for gases such as Carbon Monoxide (CO), Nitrogen Dioxide (NO2), Ozone (O3) and Sulfur Dioxide (SO2).

Supplier: Honeywell

Technology type: Industrial Gas Sensors

The sensors are highly specific to the gas they measure while still responding to some degree to other gases, which is achieved through individual compensation for temperature and cross sensitivity.

With the growing public awareness and demand for better air quality, there is a rising need for lower-cost, easily transportable solutions for air monitoring. The AQ7 Series gas sensors are designed to meet these demands with their high resolution, low detection limit and accurate environmental compensation. The sensors are a drop-in replacement for other AAQ competitors’ sensors and provide a high correlation with control stations.

These sensors are suitable for a wide range of applications including AAQ mini stations, portable AAQ systems, AAQ UAVs, aerial vehicles, urban air monitoring networks, national air monitoring networks, roadside air monitoring, industrial perimeter monitoring, environmental impact assessments, research and consultancy projects, and short-term hot spot monitoring. Get your AQ7 Series gas sensors today and ensure the air quality you and your environment deserves.
