Osiris Airborne Particulate Monitor
Airborne Particulate Monitor
The Turnkey Osiris is a versatile, real-time particulate monitor designed for ambient air quality, dust and environmental monitoring applications.
Using Turnkey’s proven nephelometer technology, the Osiris continuously measures TSP, PM₁₀, PM₂.₅ and PM₁ concentrations simultaneously, providing high-resolution data for both short-term surveys and longer-term monitoring programmes.
The Osiris can be used as a portable instrument for spot measurements or installed as part of a semi-permanent monitoring station. Flexible power options, including mains, battery and renewable power, allow deployment across a wide range of sites and monitoring environments.
Environment Agency MCERTS certification for PM₁₀ and PM₂.₅ provides confidence in measurement performance for professional environmental monitoring applications.
Flexible Environmental Monitoring
For longer-term installations, the Osiris can be integrated with meteorological sensors and other environmental monitoring equipment. Wind speed and direction, temperature, humidity and rainfall can be recorded alongside particulate concentrations, providing additional context for identifying dust sources and assessing environmental impacts.
Data can be managed using Turnkey AirQ software, supporting real-time monitoring, data retrieval, analysis and reporting.
