NEW TO AIR-MET | Aeroqual AQS1 Compact Air Quality Monitor
Air-Met is pleased to announce the newest arrival to the Aeroqual ambient air quality monitoring line up - the AQS1 compact air quality station which will be joining the likes of the Aeroqual AQM65 Ambient Air Monitoring Station and the Aeroqual Dust Sentry Dust Monitor.
What is the AQS1?
The AQS 1 combines a nephelometer, PM2.5 sharp cut cyclone, and Aeroqual’s industry leading GSS (gas sensitive semiconductor) ozone sensor technology. Housed in a rugged, lockable weatherproof enclosure, the monitor is lightweight (less than 13kg) and can be installed and moved with ease.
The AQS 1 can be configured to measure PM2.5 and ozone simultaneously, or PM2.5 only, or ozone only. It can also be configured to measure other particle fractions e.g. TSP, PM10, and PM1. Because it is modular you may order the unit with just PM2.5 for example and add ozone at a later date (without returning to the factory).
Numerous field tests have shown our GSS ozone sensor correlates very closely with US EPA / EU reference equivalent instruments. It has excellent sensitivity (down to 1 part-per-billion) and is not cross sensitive to other pollutants such as nitrogen dioxide, which is a common issue with other O3 sensors. The sensor is minimally affected by changes in temperature and humidity. That allows the AQS 1 package to deliver similar Near Reference data quality as the AQM 65 (see field test results below).
The AQS 1 is a fully integrated monitor. It includes an industrial PC which runs an embedded software system for remote technical support, data management and analytics. The PC has storage for more than 5 years of data, and it includes WIFI and Ethernet connectivity as standard features. Data transmission over cellular network is possible with the inclusion of an optional modem.
Like all of Aeroqual’s ambient air monitoring stations the AQS 1 runs Aeroqual Connect, Aeroqual's instrument operating system and can be used with Aeroqual Cloud, a cloud-base data acquisition system. Connect and Cloud allow for advanced data analysis and remote technical support.
Why did Aeroqual make the AQS1 and how is it different to the AQM 65?
A lot of customers have expressed interest in measuring gases alongside particulate matter. The AQM 65 air monitoring station is one option. But some customers don’t need to measure multiple gases (the AQM 65 can measure up to eight) – they just want to measure one or two. The AQS 1 is therefore an instrument for those seeking to answer targeted air quality questions.

How does the AQS 1 Perform?
In field tests the main thing the Aeroqual team wanted to check was the effect of temperature on the ozone sensor. Having run thousands of Dust Sentries in the field, the team at Aeroqual already knew that the particle monitor technology performed well in a non-temperature controlled environment. The team had some field experience with the Aeroqual range of portable ozone monitors and lab tests show that the ozone sensor is stable in various temperature conditions, but the team wanted to check temperature and/or humidity effects in real world conditions.
