Osiris – Complete package

Our Osiris air monitoring device measures airborne particles. The Osiris combines versatility with accuracy and is suitable for various locations and scenarios.

It can be used for short- and long-term studies, simultaneously measuring TSP, PM₁₀, PM_2.5 and PM₁ particles with a resolution of 0.1 µg/m³. In workplace mode, it will indicate inhalable, thoracic and respirable concentrations.

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 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 PM10 and PM2.5 data recording.

Osiris includes a Peli carrying case, charger, USB PC Link, TSP Head, Zero Filter, Spare filter,  Allen Keys, Software licence card, operating instructions and maintenance book, Environmental cabinet, Internet comms box, temperature-controlled inlet, rain hood, one box(100) 25mm dia, 5-micron filter membranes, 1off Dwyer Flow Meter.

How it works

The Osiris and our other airborne particle monitors work 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 can analyse individual particles, even if there are millions of particles per litre.

Additional optional accessories include an Environmental case, an Anemeter, a Heated inlet, a Temperature control inlet, a Dustmate heated inlet and a Temperature and Humidity Sensor. Speak to our technical team for more information.
