Droplet Instrumentation

Cloud Condensation Nuclei Counter (Model: CCN-100)

A CCNc is an instrument designed to count the number of particles which will activate to form cloud droplets at a specific supersaturation. A particle's ability to form a cloud droplet is important in terms of radiative effects and removal processes, and depends on its size and chemical composition. Its fast response time allows use in either airborne or ground-based stations.

Monosize Droplet Generator (Model: TSI MDG100)

The MDG produces a stream of uniform size drops in the range of 100 micro to 300 micro. It is commonly used for fundamental droplet studies like vaporization, combustion, levitation, and surface interaction. It is also useful for verification and calibration checks for various instruments.

Phase Doppler Particle Analyzer (Model: TSI PDPA TM250)

It provides accurate and reliable flow velocity, spherical particle concentration and size data from all measurement situations-from simple flows to high speed, low to high SNR situations. This instrument is best suited for spray diagnostics and turbulence measurements within the droplet size range of 0.5 µm to 500 µm. It has up to 800 MHz sampling rate and photon-counting level sensitivity. Measurements are made at a small, non-intrusive optical probe volume defined by the intersection of two laser beams.
