Condensation Particle Counters

TSI introduced its first Condensation Particle Counter (CPC) in 1978. Since then, we have developed the technology further, working together with the research community

Condensation Particle Counters

Today we have the most modern, reliable and successful selection of CPCs, operating with water, butanol, isopropanol or diethylene glycol.

The applications for CPCs are very numerous. CPCs are used around the world to count particles in air accurately—either in laboratory setups, in sensitive environments (schools, workplaces), in vehicle emissions, or in the atmosphere to monitor air quality. Our CPCs detect particles as small as 1 nm, count particles with up to 50 Hz and complement our fast-scanning nanoparticle sizer (SMPS).

TSI has a great depth of experience in designing and manufacturing CPCs, and in supporting users in their CPC applications. With so many choices, let us help you to find the solution to your measurement challenge.

Condensation Particle Counter 3750

As our only full-flow Condensation Particle Counter (CPC), the 3750 provides optimal counting statistics, making it ideal for low-concentration applications.

High Concentration Condensation Particle Counter 3752

The specialist for very high concentrations features an extended single particle counting concentration range topped with a photometric mode. TSI Condensation Particle Counters (CPCs) are the most referenced Condensation Particle Counters, backed up by 40+ years of experience. The 4th generation makes the best CPCs even better: Providing easier use for everyone with an intuitive direct-touch user-interface, new software and secure internal data storage for months of data. Improved performance, new features and diagnostics make it the best CPC in the market.

Ultrafine Condensation Particle Counter 3756

This Condensation Particle Counter (CPC) is the long-standing reference for counting ultrafine particles down to 2.5 nm. TSI CPCs are the most referenced Condensation Particle Counters, backed up by 40+ years of experience. The 4th generation makes the best CPCs even better, providing easier use for everyone with an intuitive direct-touch user interface, new software, and secure internal data storage for months of data. Improved performance, new features and diagnostics make it the best CPC in the market.

Condensation Particle Counter 3007

Mobile instruments like this Condensation Particle Counter (CPC) are designed to measure particle concentrations in the field. This Handheld CPC can be used to assess concentrations or emissions in larger buildings or areas, such as schools, workplaces, hospitals and other sensitive environments. With performance comparable to scientific instrumentation, the results captured with this CPC are very reliable.

Versatile Water-Based Condensation Particle Counter 3789

Water-Based Condensation Particle Counters (WCPCs) deliver accurate concentrations of particles in gases while making use of safe, eco-friendly and easily available distilled water. When combined with a particle sizer, nanoparticle size distributions and concentration can be quantified from <2 nm to nearly 1,000 nm. The 3rd generation of WCPC comes with numerous enhancements: + Unprecedented reliability + Low maintenance + Selectable cut-off particle size

Condensation Particle Counter 3750-CEN10

The Condensation Particle Counter (CPC) 3750-CEN10 is designed in full compliance with EN 16976:2024*. This CPC ensures precise monitoring of ultrafine particles (UFPs) in the atmosphere, meeting the highest standards of accuracy and reliability.

1nm Condensation Particle Counter 3757-50

By pairing the TSI® Condensation Particle Counter (CPC) 3750 with the Nano Enhancer 3757, the 1nm CPC 3757-50 is created. The 1nm CPC can be used as a standalone CPC, or it can be employed within a 1nm Scanning Mobility Particle Sizer™ (SMPS™) system.

Condensation Particle Counter 3750-10

The Condensation Particle Counter (CPC) 3750-10 is designed to ensure precise monitoring of ultrafine particles (UFPs) in the atmosphere, meeting the highest standards of accuracy and reliability.
