Condensation Particle Counter 3750
The Condensation Particle Counter (CPC) 3750 is a next-generation nanoparticle counter designed for precision measurements down to 7 nm (D50). Using butanol as the working fluid and operating at a consistent 1 L/min flow rate, the CPC 3750 delivers highly reliable performance across research and industrial applications. It seamlessly integrates with SMPS™ configurations, making it ideal for real-time aerosol studies, filter testing, and atmospheric research.
