Experience makes the
Experience makes the difference PARTICULATE MONITORS We can integrate a variety of different particulate monitors into your AQMS, but our preferred solution is the Acoem Spirant ® BAM, offering a high level of performance and international approvals for PM 10 and PM 2.5 monitoring. METEOROLOGICAL SENSORS Meteorological sensors used in our systems are sourced from the world’s leading manufacturers. We choose the highest quality sensors to ensure trouble-free operation. AUTOMATIC CALIBRATION SYSTEM Our air monitoring systems incorporate a state-ofthe-art dilution gas calibrator, traceable calibration gases and a high performance zero air generator to calibrate all analysers in the system. Our calibration system is fully automatic and can be remotely configured. ENCLOSURES A variety of air-conditioned shelters is available for the system, including mobile vans, caravans and relocatable shelters. If required the system can be installed in your pre-existing shelter. Our most popular shelter is our relocatable unit which is designed to be permanently sited but can be easily transported from one site to another on the back of a suitable truck or permanently mounted on a truck for mobile air monitoring studies. CONGREGO® DATA ACQUISITION Our next generation total data control and logging hardware/software solution for air quality and continuous emission systems, Acoem Congrego® is engineered from the ground up to achieve accurate, reliable, real-time data logging specifically for ambient air and continuous emission monitoring systems. SERVICE CONTRACTS You can choose to operate your own monitoring systems or take advantage of an Acoem’s service contract. Our contracts are fully customisable and can include maintenance, calibration and data reporting services. In many cases Acoem customers rely on us to provide a complete package of services which then allows us to offer NATA-endorsed data reports (refer to our Environmental Reporting Services brochure or contact us for more information).
Measurement parameters Acoem Ambient Air Quality Monitoring Systems are capable of measuring almost any gas present in the atmosphere, as well as a wide range of meteorological parameters.
