MODELS SMPS+C & 11-D

WIDE RANGE AEROSOL RESEARCH IN LABS

5 nm to 32 µm in unrivaled precision

The Indoor Wide Range Aerosol Spectrometer combines two technologies for particle counting and classifying:

a Scanning Mobility Particle Sizer (SMPS+C) with a butanol condensation particle counter for nanoparticles and the portable optical aerosol spectrometer (11-D) for dust particles.

The system can be used for accurate and high resolution measurements of the entire particle size range from 5 nm to 35 μm in 71 particle size channels. The system is easy to operate and suitable for all kind of aerosol research.

Overview

  • real-time monitoring of the entire particle size range
  • high precision with CPC and OPC at low and high concentrations
  • excellent counting statistics and reproducibility
  • low diffusion losses
  • self-test of all optical and pneumatic components for high quality standards
  • instrument parameters secured against data loss

Applications

  • monitoring of ultrafine particles and dust
  • aerosol science
  • workplace monitoring
