Particle Counter R306

Model R5501P-30 Large Particle Counter

0.5 – 75 µm @ 0.1 CFM with long-life internal pump

The Airy Technology® R5501P-30 Remote Particle Counter measures 0.5 to 75.0 µm with a flow rate of 0.1 CFM (2.83 LPM) from an internal vacuum pump, and is the most feature-advanced remote particle counters available. Integration is easy into a building automation and clean room management system via Ethernet, or (optional) Wireless 802.11 b/g, RS485 or RS232.

The R5501P-30 remote particle counter displays and reports 6 user-selectable particle size channels, as well as (optional) temperature and relative humidity, flow and sensor status, date of last calibration, serial number, laser on-time and date of manufacture for easy maintenance and warranty management. This remote particle counter stores up to 45,000 time stamped particle count and environmental data records which provide data redundancy on every instrument. Airy Technology® counters can be monitored remotely via web browser, or controlled and monitored using IMS Software.

All Airy Technology® counters meet ISO 21501-4 and JIS B9921. The R5501P-30 ensures compliance with an on-board pulse height analyzer.
