Dust Monitors


ECOTECH designs and integrates a wide range of continuous particulate monitors including light scattering based PM monitors and beta attenuation monitors.

Our monitors can be incorporated into air conditioned weatherproof shelters or can be stand alone powered by solar panels. We offer a wide range of solutions for many different types of industries including mining, construction, pulp & paper, cement manufacturing, aluminium smelting and compliance monitoring of all types.

ECOTECH are the distributor of the Met One, Opsis and MSP range of particulate monitors. We also design and manufacture our own range of continuous aerosol monitors including the Aurora integrating nephelometer and high and low volume air samplers.

ECOTECH supplies dust/particulate samplers and monitors for TSP, PM2.5 and PM10. Ecotech also produce the world's largest range of nephelometers, used to measure visibility along with other applications involving the scattering of light by aerosols used in global radiation balance studies.


Met One BAM 1020 Beta Attenuation Monitor - Compliance Applications

The BAM-1020 automatically measures and records airborne particulate concentration levels (in milligrams or micrograms per cubic meter) using the industry-proven principle of beta ray attenuation. Thousands of BAM-1020 units are currently deployed worldwide, making the unit one of the most successful air monitoring platforms in the world.


The Met One Instruments Model BAM-1020 has long standing U.S. EPA designation as a Federal Equivalent Method (FEM) for continuous PM10 particulate monitoring. In addition, the BAM-1020 is the world’s first instrument to obtain U.S. EPA FEM designation for continuous PM2.5 monitoring, when configured with the specified settings and accessories. The BAM-1020 has also obtained corresponding certifications in other countries and regions.

The BAM1020 meets Australian Standard AS/NZS 3580.9.11:2008 Method 9.11: Determination of suspended particulate matter – PM10 Beta Attenuation Monitor.


Met One E-BAM Beta Attenuation Monitor

The Met One E-BAM is a portable real-time beta gauge traceable to US-EPA requirements for automated PM 2.5 and PM 10 measurement. It is also ideal for the monitoring of TSP.

It can be used as a TSP, PM10 or PM2.5 monitor depending on the size selective inlet which is used.

The E-BAM meets Australian Standard AS/NZS 3580.9.11:2008 Method 9.11: Determination of suspended particulate matter – PM10 Beta Attenuation Monitor.

The E-BAM provides continuous filter tape measurement of PM concentrations. 15 minute averages are available and it can interface with meteorological sensors which include wind speed and direction, relative humidity and temperature. It is installed in hundred's of sites throughout Australia, especially in the mining industry, and is an excellent solution for remote monitoring where AC power is unavailable. Ecotech's Wincollect interfaces directly to the E-BAM and is able to automatically download data remotely.


Met One E-Sampler

The E-SAMPLER is the most feature-packed light-scatter Aerosol Monitor available.

Whatever your monitoring needs, the E-sampler will provide accurate, dependable and relevant data.

Opsis SM200 Particulate Sampler/Monitor

The Opsis SM 200 is a combined particulate monitor that can be used for both automatic measurement and filter sampling. It uses 47 mm filters for sampling and beta attenuation of particulates.

It is a sequential sampler that can contain up to 40 filter cartridges allowing later chemical analysis.

It can also be fitted with a real time light scatter PM monitor in order to provide real time data.
