3501 Remote Airborne Particle Counter
with internal brushless pump 0.1 CFM (2.83 LPM)

The Particles Plus 3501 Series Remote Particle Counter with a long life internal 0.1 CFM (2.8 LPM) brushless pump is the most feature-rich, advanced remote particle counters available. Easily integrated into building automation and cleanroom management systems via Ethernet, USB, RS485/RS232 or (optional) Wireless 802.11 b/g, the 3000 Series' internal vacuum pump makes installation simple and highly cost effective.

The 3000 Series remote particle counter reports 6 user-selectable particle size channels, internal flow, sensor status, date of last calibration, serial number, laser on-time and date of manufacture for easy maintenance and warranty management. Onboard self-diagnostics monitor laser power, temperature and life, pump temperature, power and flow, while monitoring all communications between each Intelligent subsystem and the internal processors.The Particles Plus MODBUS™ register map provides the most comprehensive reporting and control functions available of any remote particle counter. The user-selectable MODBUS™ protocols, including ASCII, RTU, & TCP/IP enable simple and easy connectivity to any monitoring system. The industry's most full-featured, dedicated communications controller is unsurpassed as it handles many concurrent operations such downloading records locally while simultaneously communicating on a MODBUS network, and also serving up multiple external browser interface sessions.

These remote particle counters offer an internal memory that stores up to 45,000 time-stamped particle count data records, providing data redundancy on every instrument.

All Particles Plus counters meet ISO 21501-4 and JIS B9921.The model 3501 ensure compliance with an on-board pulse height analyzer.
