Air Quality Particle Counter Meter P311

PRODUCT DESCRIPTION

Laser particle meter for measurement in cleanrooms or conventional rooms / 
Storage capacity for 8,000 data sets / data sets stored as *.csv files / 
max. concentration: 4,000,000 particles per ft3 / laser particle meter with internal pump

The laser particle meter is not only designed for cleanrooms, but also for evaluation and classification of the air quality in conventional rooms. The laser particle meter detects by means of laser technology smoothly slightest air pollutants of 0.0003 mm (0.3 µm) calibre up to 0.005 mm (5 µm). At the especially large coloured display three particle sizes can be shown simultaneously. Despite a low weight and compact measures the laser particle meter delivers reliable results and is especially easy to handle and very light. The 8,000 data sets will be displayed on the large coloured display and can be easily transferred via USB to a computer. The data will be stored as *.csv files and can be read and revised via Excel.
