Condensation Particle Counter 3775

SKU: 3775

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

Condensation Particle Counter 3775 is a general-purpose counter that detects airborne particles down to 4 nm. It provides highly accurate measurements over a wide concentration range from 0 to 10 7particles/cm 3. As a result, this CPC is quite versatile and well-suited for a broad range of applications.

*A newer model of this product is now available.

Product Details

The successor to the Model 3022A, the Model 3775 features extended single particle counting with continuous, live-time coincidence correction for concentrations up to 50,000 particles/cm3. A photometric mode takes over at higher concentrations. The 3775 also features an improved transition between the two count modes. It has a color VGA display, anti-spill design, water-removal capability, data logging and storage capabilities with a removable memory card, and USB and Ethernet ports. It includes built-in SMPS™ compatibility and our Aerosol Instrument Manager® software.
