|Name||DMT dual-channel Cloud Condensation Nuclei Counter|
|Manufacturer||Droplet measurement technologies|
|Name||Condensation Particle Counter (CPC)|
|Acronym||Condensation Particle Counter|
|Measured parameter||Number concentration of submicrometer aerosol particles|
The particles are detected and counted by a simple optical detector after a supersaturation vapor (butanol or water) condenses onto the particles, causing them to grow into larger droplets. The CPC uses a (laser diode) light source, a condensing lense, an internal microprocessor control, volumetric flow control and a front panel display.
|Measurement(s)||Clouds & Precipitation|
|External dimension||Internally mounted on 19 inch racks. 32.0â€H x 15.25â€ W x 10.6 D / 81.3 cm H x 38.7 cm W x 27 cm D|
|Operating mode||In situ|
Samples not to be taken in cloud or heavyvy precipitation.
Intake via Rosemount housing intake.
20A at 28VDC
Certified for FAAM Bae146
Continuous-flow thermal diffusion chamber. Activation of CCN particles at constant supersaturation maintained in a 50-cm-high column with continuously wetted walls and a longitudinal thermal gradient; sizing of the activated droplets using an optical particle counter
