TOPAS 1® Laser Arosol Particle Counter LAP 340 Advantages Portable particle counter for stationary as well as mobile use 镕 Complies with the following standards: VDI 2083 DIN 1946 DIN 12950/12980 US Federal Standard 209 E DIN EN 14644 Automatic calibrating function enables an easy checking and recalibration of the system Օ User-friendly software for measuring and archiving Quick instrument setup Applications Օ Validation and monitoring of Clean rooms and Laminar air flow boxes Emission measurement (e. g. vacuum cleaner testing) Օ Fractional efficiency tests of filters and separators Laminar Air Flow Box Laser Arosol Particle Counter LAP 340 Laser Arosol Particle Counter LAP 340 The particle counter LAP 340 is a mobile useable 驩valuation system for measuring the number and size of particles in air streams and gaseous media. The measuring range comprises 0.3 ... 10 |_im in 16 particle size channels at a flow rate of 28.3 l/min. This makes it suitable for a variety of measuring tasks. These include monitoring and checking of clean rooms, clean benches, filter facilities in operation rooms or filling facilities in the pharmaceutical industry. Another area of application, especially in connection with the Topas Dilution System Series DIL, are separation efficiency tests of filters. An LCD display allows during the measurement an overview of various data such as particle size channels, date, time and the current measurement. The measuring results are shown in a table. At the end of the measurement, a thermal printer enables a print out of the data together with threshold value exceedings and sample identification. With the in-house developed Topas software package PASWin further processing of the measuring results can be done in programs like MS Excel. The software also allows direct measuring and archiving.
