We run one of the largest air quality testing operations in the country. Our ambient air monitoring department has more than 50 monitoring stations across New Zealand, and our team has years of experience monitoring air quality. Using state-of-the-art technology, our team measures dust, and particulates. Our testing equipment can be installed on almost any site and is programmed to automatically capture samples. The types of testing we can carry out include measuring Total Suspended Particulates (TSP), PM10 and PM2.5 over a set period using a gravimetric sampler or in real time using a beta attenuation monitor (BAM). 

The list below gives you an idea of what our team can test for.

Scope of test

Total Suspended Particulates

These particles refer to the totality of small solid matter measured in the atmosphere. Total suspended particulates are the primary contributor to air pollution


These particles can be found in dust and smoke, soot, and salts. They have a diameter of 10 micrometres (0.01 mm) or less. PM10 particles are a common air pollutant


These particles are exceptionally fine particulate matter with a diameter of 2.5 micrometres 0.0025mm) or less. PM2.5 are tiny particles in the air that reduce visibility and are a common air pollutant. They can penetrate deeper into the lungs than the other particulate matter mentioned above
