Water-based Condensation Particle Counter 3785

SKU: 3785

This instrument was discontinued as of January 1, 2010.

*A newer model of this product is now available.

Product Details

This model has been replaced by the Next Generation of Water-based Condensation Particle Counters, including the General-Purpose Water-based CPC Model 3787 and the Nano Water-based CPC Model 3788.

The Model 3785 Water-based Condensation Particle Counter* uses water to enlarge particles for easy detection. The Model 3785 detects particles from 5 to >3000 nm. It provides a wide, dynamic, particle-concentration range. Featuring both a single-particle-counting mode with continuous, live-time coincidence correction and a photometric mode, this particle counter measures concentrations up to 10 7 particles/cm 3 with high accuracy. It offers quick response and is compatible with our SMPS systems.
