Condensation Particle Counter 3750-CEN10

SKU: 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.

Product Details

The CPC 3750-CEN10 builds on a multi-generation lineage of TSI® full-flow CPCs, which have served as the gold standard in nanoparticle counting for several decades. The new updates extend the concentration range, provide easier use for everyone with an intuitive direct-touch user interface, new software, and secure internal data storage for months of data.

Built on decades of experience with particle counting technologies, the CPC 3750-CEN10 is made for 24/7/365 operation. When complemented with accessories for sampling – as well as temperature and humidity measurement – the resulting system is the cornerstone of your ambient air monitoring station. For hot-spots of ultrafine particles (UFPs) with high concentrations, a diluter is available.

With the goal of bringing consistency to the measurement of UFPs in ambient air, EN 16976:2024* outlines precise criteria for both the CPC and the accompanying Sampling System. The 3750-CEN10 CPC meets all criteria specified in EN 16976:2024.

In addition, the 3750-CEN10 is fully integrated into the Scanning Mobility Particle Sizer™ (SMPS™) family. The SMPS™ 3938W50-CEN10 enables ambient air monitoring stations to measure size distributions of ultrafine particles in compliance with CEN/TS 17434:2020.
