P311 Laser Particle Counter

Laser particle counter for measuring clean rooms and conventional spaces / memory for 8,000 data series / *.csv format / max concentration: 4,000,000 particles/m³ / laser particle counter with internal pump

The laser particle counter has been designed not only for use in clean rooms but also to assess and classify air quality in conventional spaces. The laser particle counter detects the smallest air pollutants through its laser technology, in a thickness range of 0.0003 mm (0.3 µm) to 0.005 mm (5 µm). The large color display allows simultaneous visualization of three particle sizes. Despite its light weight and compact dimensions, the laser particle counter provides reliable results and is especially easy to use. The 8,000 data series are displayed on the large color screen and can be easily transmitted via USB cable to a computer. The data series are stored as *.csv files and can be read and edited in Excel.
