Mixing Condensation Particle Counter (MCPC)

Model 1720

Features

For applications requiring a particle counter capable of rapid total number concentration measurements down to a few nanometers – the Model 1720 Mixing CPC is packed with features in a very compact package. The particle counter has been deployed on ships, aircraft, on top of Mauna Loa and at the South Pole – with proven low pressure operation, the unit is ruggedized for field use.

  • 180 ms ultra-fast time response
  • 7.0 nm 50% detection diameter
  • On-board data storage
  • Tilt tested anti-flooding design
  • Extremely compact and lightweight
  • Proven continuous 24/7 operation
  • Fully characterized

Benefits

  • Independently proven 100% counting efficiency
  • Ideal for rapid DMA scanning
  • Low butanol fluid consumption
  • Resists flooding of optics block
  • Low power use and small size
  • Robust field-tested design

What’s Included

The Model 1720 MCPC comes with the following items:

  • Mixing CPC
  • Saturator flow bypass tubing assembly
  • Butanol fill bottle
  • Detailed instrument manual
  • RS-232, USB and BNC cables
  • Graphical user interface software for Windows PC External AC-DC power supply with AC power cord

Software

The MCPC software has been designed with ease-of-use in mind. All of the instrument operating parameters are quickly accessible either via the graphical user interface (GUI) software provided for your computer or directly from the instrument front panel using the data knob. Coincidence-corrected concentrations, raw concentrations, counts or summed counts over a specific time period can be obtained from the front panel display or via the GUI software.

Changes to instrument settings may also be made either through serial commands or directly through the front panel display. Settings include displayed concentration/count/sum type, whether labels are reported for each parameter, communication baud rate as well as calibration coefficients for sample and saturator laminar flow elements. Software tools to easily re-calibrate or validate calibrations of key components like LFEs are provided so you can verify proper operation of the instrument.
