CONDENSATION PARTICLE COUNTER MODEL 3752

THE SPECIALIST FOR HIGH CONCENTRATIONS

The 4th generation of TSI Butanol-CPCs (Condensation Particle Counters) include a High-Concentration CPC that now detects up to 100,000 particles/cm³ in single-counting and further up to 10,000,000 particles/cm³ (photometric detection). This high concentration model features an intuitive direct-touch user-interface, new software, improved reliability, and secure internal data storage for months of data. Modern communication options, wired or wireless, let you connect to your device remotely and ultimately optimize your particle research.

Features and Benefits

• Extended single-counting concentration range up to 100,000 particles/cm³
• Photometric concentration up to 10,000,000 particles/cm³
• Detect particles down to 4 nm (D50)
• Data rate up to 50 Hz - Capture highly dynamic processes
• Water-removal system - Compatible to high-humidity environments
• Improved Diagnostics with Pulse Height Monitoring

The High Concentration CPC model 3752 fits seamlessly into the family of four Butanol-based CPCs including the Standard model, the Ultrafine Particle and the 1-nm model, and is fully integrated into the SMPS¹ family series 3938. With its concentration and size range it serves all applications from filter testing, basic aerosol research, combustion, health and atmospheric studies specifically for high concentrations such as polluted areas (harbors, mega-cities, etc.).

All TSI CPCs are equipped with a removable saturator wick for easy transport and maintenance, as well as anti-flooding features and pulse height monitor for reliable, good measurements.

¹ SMPS stands for Scanning Mobility Sizer, another reference system by TSI to measure nanoparticle size distributions.
