LAP 322 - Aerosol Spectrometer
The Aerosol Particle Size Spectrometer LAP 322 provides the determination of aerosol particle size distributions (0.2-40µm) and particle concentrations. It is based on optical single-particle measurements by means of 90° scattered light measurement.
By dint of high number of provided particle size classes a high particle sizing resolution can be realised, as well as a very good classification accuracy (VDI 3867, Part 4 and ISO 21501-1).
The aerosol spectrometer LAP 322 combines sensor, controlled volume flow supply, and signal acquisition in one rugged, handy housing. The included Data Acquisition and Control Software PASWin for standard Windows PCs provides for an easy operability.
Advantages
- Rapid optical measurement of airborne particles – minimal disturbance of aerosol properties
- Very big dynamic range of particle size: 200nm ... 40µm (with just one sensor)
- Wide concentration range (max.104particles/cm3) - ideal for filter testing
- Easy and defined extension of concentration measuring range by use of Dilution Systems (DIL 550)
- Optimized measuring zone:
- no border zone --> no border zone error
