12000 Ambient Air Monitor

Condensation Particle Counter & Optical Particle Counter

The Particles Plus 12000 is the first real-time dual mode ambient monitor to feature both a condensation particle counter and an optical particle counter in an integrated unit. The 12000 condensation particle counter is designed to detect and count aerosol particles by first enlarging the particulates using a supersaturated vapor. These robust monitors provide reliable, accurate measurement of airborne particles across a very wide size range (from fines to ultrafines) allowing for the detection of environmental and public health concerns involving airborne particulates.

Realtime Data
The optical particle counter (OPC) bins fine particulates in up to 30 particle size channels (from 0.3 μm to 10 μm) which are stored in on-board memory at a user-defined data sampling rate (1 second to 99 hours per sample). The condensation particle counter (CPC) measures ultrafine particulates as small as 5 nm (0.005 μm) and provides a total particle count above this threshold, this data is also stored in each of the above samples to provide a more complete view of air quality.

Internet-Enabled
Particles Plus systems are configured to allow users to push real-time data to the cloud where sensor outputs can be visualized by authorized stakeholders.
