Aerosol Spectrometer LAP 322

The LAP 322 Aerosol Particle Size Spectrometer provides the determination of aerosol particle size distributions (0,2 - 40 µm) and particle concentrations.

Standards

The LAP 322 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.

Benefits

• measuring range of particle size: 200 nm … 40 µm (with just one sensor), various measuring ranges selectable
• Wide concentration range: from 1 to max. 1E4 #/cm³ ) – ideal for filter testing
• easy and defined extension of concentration measuring range by use of Aerosol Dilution Systems
• high counting efficiency of > 50% already at 200 nm
• light source with long life time (20,000 h) by use of approved laser diode
• high size resolution by means of multi channel analysis with > 90 size channels
• incl. ease of use and comprehensive Windows based control and analysis Software PASWin
• easy control of Sample Switching Unit SYS 520 for measurement of fractional efficiencies
