Topas - Particulate Monitoring System


Topas - Environmental TSP, PM10, PM2.5 and PM1 Monitoring

Topas (Turnkey Optical Particle Analysis System) is a fixed station monitor designed to continuously record environmental TSP, PM10, PM2.5 and PM1 particles. Topas has achieved the Environment Agency's MCERTS certification, ensuring its accuracy in recording data.


The instrument is housed in a compact, unobtrusive stainless steel wall box with IP66protection. Inlet heating is fitted as standard. All controls and displays are located behind a lockable door.


Several sites can be networked together to form a city wide monitoring system. Sites can be connected by radio, telephone or GSM modems, internet connection or fixed wiring and controlled by one PC using AirQ software.


Osiris and Topas also allow wind speed and direction, temperature, humidity, rainfall and two external gas or noise meter inputs to be recorded at the same time.
