FromTopas GmbH
The particle counter LAP 340 is an device for measuring the number and size of particles in air streams and gaseous media. It is identical in construction with Abacus mobil air and is built by Klotz GmbH on behalf of Topas. The measuring system is suitable for stationary as well as mobile use. The device 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). 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.
