Ultrafine Condensation Particle Counter 3776

SKU: 3776

This model has been discontinued as of March 31, 2018.

The Ultrafine Condensation Particle Counter 3776 (UCPC), a types of condensation particle counter (CPC) is designed primarily for researchers interested in airborne particles smaller than 20 nm. It is a continuous-flow instrument that detects particles down to 2.5 nm. It uses a special sheath-air flow design that improves response to changes in particle concentration and increases counting efficiency for ultrafine particles.

*A newer model of this product is now available.

Product Details

The successor to our Model 3025A, the 3776 has a higher aerosol flow rate and better flow control. It features extended single particle counting with a continuous, live-time coincidence correction up to 300,000 particles/cm3. It has a butanol-friendly, anti-spill design with water-removal capability. It includes a color display, built-in data logging and storage capabilities with a removable memory card, and USB and Ethernet connectors. It comes SMPS™-ready, right from the factory, and it includes our Aerosol Instrument Manager® software.
