Turnkey is a leading developer and manufacturer of environmental monitoring instrumentation and brake testing and vehicle compliance testing equipment.
All of our monitoring and testing equipment has been developed in-house by our skilled engineers. We pride ourselves on creating accurate, reliable equipment which is practical and user friendly.
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.
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 data.
The DustMate environmental monitor is our handheld dust and fume detector and is perfect for short-term sampling.
Versatile and practical, this handheld device is ideal for short-term testing of air quality in buildings, workplaces and on the roadside. With a very fast response time, it delivers accurate readings and can locate sources of airborne dust and fumes even at very low concentrations.
Highly effective for monitoring air quality, the DustMate measures TSP, PM10, PM2.5 and PM1 simultaneously in real time.
It will also continuously indicate the concentration of thoracic, inhalable and respirable particles down to 0.1 µg/m3.

The Topas is a fixed station monitor and is housed in a small, lockable unit which can be wall mounted in a convenient location on site.
Topas stands for Turnkey Optical Particle Analysis System. Designed to continuously record environmental TSP, PM10, PM2.5 and PM1 particles, it offers a comprehensive testing and monitoring solution for construction sites, manufacturing sites and industrial operations, as well as local authorities and other organisations.
The Topas has been Environment Agency MCERTS certified so users are guaranteed reliable and accurate recording of PM10 data. It is straightforward to use, can be easily wall mounted, and all controls and displays are located behind the lockable door.
