Environmental Particle Counters

Recent research has uncovered that large amounts of small airborne particles may be present from sources like traffic, residential heating, but they contribute little to particulate mass. Today, monitoring networks increasingly use Condensation Particle Counters (CPCs). These tools supplement gravimetric PM measurements with real-time measurements of particle number concentration.

TSI’s line of environmental particle counters are in use around the world, accurately measuring and reliably reporting atmospheric particle concentrations. Our water-based 3783 Environmental Particle Counter operates 24/7 for up to four weeks on one liter of water, making it ideal for low interaction settings such a remote monitoring stations. For customers who must meet stringent requirements for data comparability, use model 3750-CEN, a butanol-based CPC that complies with European specification EN 16976 (formerly known as the Technical Specification CEN/TS 16976, and established by the European Committee for Standardization (CEN)).
