Condensation Particle Counter 3750

SKU: 3750

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

Product Details

For decades, TSI® Condensation Particle Counters (CPCs) have been the gold standard in nanoparticle counting. The CPC 3750, our latest innovation, continues this legacy of excellence.

Using industry-standard butanol as the working fluid, the CPC 3750 is the next generation of a CPC design that has served the nanoparticle counting community for decades. Its D50 of 7 nm provides visibility into concentrations of sub-10 nm particles, granting you invaluable insights into your nanoparticle samples. Its single flow mode – 1 L/min – simplifies your operation.

The CPC 3750 offers flexibility in operation—it can be utilized with software or independently. When used without software, data is stored directly on the CPC for future access.

Furthermore, the CPC 3750 is an important component in the most common Scanning Mobility Particle Sizer™ (SMPS™) configuration (along with TSI's Long DMA 3081A). This established configuration has a proven track record across a wide range of measurement applications.

In summary, the CPC 3750 offers an extended concentration range, optimal counting statistics, and seamless compatibility with SMPS™ technology. As the ultimate choice for researchers, scientists, and professionals in various fields, it's your key to advancing nanoparticle counting in your work. Trust in the reliability and precision that TSI® instruments have consistently delivered through the years.
