The Cleanroom Particle Counter LAP 340 is a device for measuring the number and size of particles in air streams and gaseous media according to ISO 21501-4. The measuring system is suitable for stationary as well as mobile use. The particle analyzer is especially suitable for clean room applications which enables it to cover a wide particle size range from 0.3 µm to 10 µm and a maximum measurable particle number concentration of 980,000 particles/ft3 (35 particles/cm³), in the standard version. That opens a wide range of measuring tasks.
These include monitoring and checking of clean rooms, clean benches, filter facilities in operation rooms, filling facilities in the pharmaceutical industry and separation efficiency tests of filters.
