The PM100 particulate monitor is used for continuous measurement of α and β particulate volumetric activity in all gaseous effluents.

The sample is pulled by means of a pumping unit from the flow of an exhaust stack, a ventilation duct or the static atmosphere of a working zone and then transferred to a detection assembly.

A dynamic compensation of the contribution of Radon natural daughters and a dynamic compensation of environmental γ background changes are implemented. A spectrum analysis of the α contribution is performed.

The monitor displays the measured volumetric activity and triggers alarms whenever preset threshold levels are exceeded.

The PM100 is part of the SYSRAY RMS system.

This monitor can be used as a stand-alone system or combined to :

• an iodine volumetric activity monitor
• a gas volumetric activity monitor
• a particulate & iodine sampling device
• a high volumetric gas activity monitor
