Portable Particle Counter Model 3910 Featherlight Smallest 6-channel, Portable Airbourne Particle Counter The new 3910 is the smallest 6-channel portable particle counter in the industry; it provides 50 LPM flow rate with a 0.3 micron sensitivity. With its 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 the 3910 the ultimate tool for cleanroom certification. Critical Environment Monitoring HEPA Filter Performance Testing The unit is featherlight and the smallest in the industry. Large, color touchscreen with an easy to navigate, user-friendly interface 50 L/min (1.77 cfm) flow rate speeds the sampling process. Built-in printer and onboard datalogging (up to 10,000 records). Simultaneously measures and displays up to 6 particle sizes from 0.3 to 10 microns. Stainless, cleanroom-friendly enclosure. Fully compliant with ISO 21501-4 calibration standard. Optional Climomaster environmental probe adds the ability to measure airflow, temperature, and humidity. Enables you to certify cleanrooms up to ISO Class 2. Differential pressure sensor available as an option 21 CFR Part 11 compliant with IQ/OQ documentation available An optional 2nd Li-ion battery can be installed in the unit to extend the operating time. Small Size and Lightweight Unit Multi-standard mode simplifies cleanroom ceritifcations based on ISO 14644, FS 209E, BS 5295 and EC GMP. Extended 2 year warranty.
