Portable, Direct Reading, Airborne Particle Sample

  • Battery or mains operation
  • Internal sampling pump
  • Reference filter for gravimetric calibration
  • Inputs for wind speed and direction and traffic counters
  • Outputs for inlet heaters and alarms

One of the family of Turnkey's direct reading airborne particle monitors, Osiris is a general purpose instrument which can be used as a portable instrument or deployed in a semi-permanent installation.

Fitted into a Turnkey Lamp Post Box, Osiris can be quickly deployed to study short or long term pollution hotspots in towns and cities and exceedance areas rapidly determined.

Osiris will continuously indicate the concentration of TSPPM10PM2.5 and PM1particles with a resolution of 0.1 micrograms per cubic metre. In its workplace mode, it will indicate inhalable, thoracic and respirable concentrations. Osiris has achieved the Environment Agency's MCERTS certification, ensuring its accuracy in recording data.

An internet-based server is available for Osiris, providing a web interface, camera capability and internet communication in AirQ. See more details here:
