The Flow Choice High Volume Air Sampler, manufactured by Thomson Environmental Systems , allows for validated sampling of dust particles in ambient air. The unit can be configured for TSP, PM10 or PM2.5, and the inlet heads are interchangeable.

The units are built to meet Australian Standards for high volume gravimetric sampling, and utilise a precise and versatile venturi sampling system. They are made of light weight aluminium construction and include speed controlled brushless blowers to limit noise and provide accurate, dependable flow control.

The flow choice electronic sample system controls flow rate at standard or actual conditions and logs flow rate, total volume, ambient temperature and pressure and pressure drop across the filter, allowing the user to validate all samples and ensure accuracy.

Logged data is accessible through the front panel or can be downloaded through RS232 or modem (optional). It is also possible to programme parameter checks and alarms to be sent through SMS (optional).

The real time clock and easy to use keypads allow for 3 or 6 day programming. All units are supplied with 2 filter holders for easy field exchange, allowing all filter handling to occur in a clean lab environment.
