The gold standard in nanoparticle counting for many decades is now updated with newly extended size and concentration range.

TSI CPCs are the most referenced Condensation Particle Counters, backed up by 40+ years of experience. The 4 th 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.

Product Details

The Standard CPC model 3750 fits seamlessly into the family of four Butanol-based CPCs including the High Concentration , the Ultrafine Particle and the 1-nm model, and is fully integrated into the SMPS™ family model series3938

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