Osiris

Our Osiris air monitoring device measures airborne particles. The Osiris combines versatility with accuracy and is suitable for use in a wide range of locations and scenarios.

It can be used for short- and long-term studies, simultaneously measuring TSP, PM10, PM2.5 and PM1 particles with a resolution of 0.1 µg/m3. In workplace mode, it will indicate inhalable, thoracic and respirable concentrations.

Product Description

The Osiris can be used as a portable instrument or deployed in a semi-permanent installation, making it the ideal monitor for studying short- or long-term pollution hotspots in towns and cities, and on sites where airborne particles are could be a concern and require monitoring.

It can be housed in a lamp post box, and in addition to the facility to power by mains or battery, the Osiris also offers the option of powering by solar or wind power where practical.

The Osiris has been Environment Agency MCERTS certified so users are guaranteed reliable and accurate recording of PM10 and PM2.5 data.

How it Works

The Osiris, along with our other airborne particle monitors, works using Turnkey’s specially-developed nephelometer. Air samples are continuously drawn through the nephelometer, which analyses individual particles as they pass through a laser beam. The particles are then collected on the reference filter. The nephelometer’s microprocessor has the capacity to analyse individual particles, even if there are millions of particles per litre.
