Hach Ultra has introduced the Met One 3400 Series of Portable Airborne Particle Counters for faster sampling, ease of use and reduced technician time. Available in two flow rates, 50 L/min or 28.3 L/min, and a sensitivity range of 0.3 to 25 microns, the 3400 offers flexibility for QA/QC and technical managers to verify critical processes and environments, including clean rooms. The 3400 Series also contains Long Life Laser technology for low cost long-term ownership, extending the instruments average laser life to more than 10 years.Lightweight and compact, the 3400 features strategically-placed handles for easy lifting: two on the sides and one on the front. The 3400 easily relocates to various sampling sites for data collection throughout a facility. A versatile form factor enables both horizontal and vertical orientations of the instrument. Most importantly, dual hot-swappable batteries minimize downtime for seamless operation.For data entry and management, the 3400s color touch-screen facilitates viewing from a greater distance in different lighting and at different angles. An intuitive, icon-driven operating system with touch commands simplifies the count collecting process. Data transfers quickly from USB ports onto a PC or flash drive, or print results immediately from the built-in printer. The counter also interfaces with PortAll Version 2 for remote scheduling and data download.For life science environments, the 3400s stainless steel construction and unobstructed surface permit quick and frequent wipe-downs. With PortAll Version 2 Life Sciences Version, the 3400 provides the necessary regulatory documentation for 21 CFR Part 11 compliance, minimizing downtime and lost product batches.
