Condensation Particle Counter (CPC) Model 5403

The only mobile high-accuracy counter for nanoparticles

Battery operated SMPS system (from 4 to 1000 nm)
Battery operated SMPS system with battery operated optical particle counter (from 4 to 30.000nm)

This universal CPC can be used in a large variety of applications due to its compact design and its integrated SMPS options. The CPC may be operated as particle counter only or in combination with one of our Differential Mobility Analysers (DMAs) as SMPS+C (Scanning Mobility Particle Sizer) to measure size distributions from 5 to 1100 nm. Through combination with GRIMM optical aerosol spectrometers (“Wide Range Aerosol Spectrometer”, WRAS), measurement of size distributions in the extended size range from 5 nm to 32 µm is possible.

Customers benefits

• CPC optimized for mobile measurements
• With integrated battery and butanol tank
• Detects particles > 4.5 nm
• Measures concentrations up to 20000 P/ccm in single count mode and up to 10^7 P/ccm in photometric mode
• Integrated sample pump, sheath air pump, and DMA controller; ready for combination with DMAs
• Self-tests to assures highest reliability of measured data


• 55-340: Electrostatic Classifier “Vienna”- M-DMA: 5 – 350 nm
• 55-900: Electrostatic Classifier “Vienna”- L-DMA: 10 – 1100 nm
• 55-U: Electrostatic Classifier U-DMA – Universal-Differential Mobility Analyser (two-in-one version)
• 5441: Carrying case for CPC 5403
• 5475: Labview Software pre-installed on 10" NETBOOK
• 5522-A: Neutraliser, Am-241, 3.7 MBq (needs licence)

The GRIMM universal software 5477 operates CPCs as counters only, and SMPS systems for measuring size distributions. It can be used for SMPS+C (CPC as detector) or for SMPS+E (Faraday Cup Electrometer, FCE, as detector).

• Measurement of size distributions in stepping mode and in fast scanning mode
• Calculation of size distributions in real time following the standard ISO 15900
• Values of external sensors and service data are integrated.
• Compatible to all 32-/64-bit Windows operating systems (XP or newer)
• Preconfigured on a netbook
• Data loggers and the online transfer of data to internet servers are supported
• Calculation of number, surface, and mass size distributions, optionally with or without various corrections, and several statistical parameters
