Topas

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, PM_2.5 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 and PM_2.5 data. It is straightforward to use, can be easily wall mounted, and all controls and displays are located behind the lockable door.
