3775 Alcohol-Based Condensation NucleiParticle Counteris a general-purpose counter that detects suspended airborne particles as small as 4nm. It guarantees highly accurate detection over a wide concentration range of 0-107 particles/cm3. This makes the CPC powerful and suitable for a wide range of applications.

3775 is the successor to the Model 3022A, which features continuous real-time calibrated extended single particle counting at concentrations up to 50,000 particles/cm3. Higher concentrations are required for photometer mode, and the Model 3775 also features faster conversion between the two counting modes. It features a color VGA display, spill-proof design with water removal, data logging and storage via removable memory card, and USB and Ethernet ports. It includes a built-in SMPS? compatible system and our Aerosol Instrument Manager? software.
