Particles Plus 5000 Series Particle Counters

Particles Plus 5000 Series Particle Counters

Particles Plus 5000 series remote particle counters are fixed particle and environmental sensors which may be used in cleanrooms, controlled environments, for indoor air quality monitoring and other indoor applications. These models are available in 1.2 LPM and 2.8 LPM variations and they are specifically designed to handle much higher concentrations of particulates than traditional (cleanroom only) optical particle counters.

The Particles Plus 5000 series are capable of displaying and logging particle counts, particle size and particle mass in ug/m3 making them ideal sensors for indoor air quality monitoring, occupational health and safety exposure monitoring, monitoring warehouses and non controlled environments. For cleanroom monitoring in accordance with the latest PIC/S PE-009-17 GMP standards, we offer a wide range of alternative 28.3 LPM remote cleanroom particle counters.

Measurement Capabilities

Particles Plus 5000 series remote particle counters may be used in cleanrooms, buildings and any environment where indoor air quality monitoring is required. A single state-of-the-art sensor per room or location can replace the need to install a whole range of separate environmental sensors which would traditionally be linked back to BMS, EMS, SCADA systems.
