Portable particle counter 3910 and 3905
Featherlight Smallest 6-channel,Portable Airbourne Particle Counter
The new 3910 & 3905 are the smallest 6-channel portable particle counters in the industry; with a 50 LPM and 1 CFM flow rate respectively and a 0.3 micron sensitivity. Both units feature a large color touch screen, streamlined, user-friendly interface and pre-programmed standards mode to guide you through the measuring and certification process it may also be the most helpful. An optional
Climomaster environmental sensor provides the ability to measure air velocity, temperature and humidity making these instruments the ultimate toolsfor cleanroom certification.
