Remote Particle Counters
R5501 Remote Particle Counter
0.5 – 25 µm @ 0.1 CFM with (optional) long-life internal pump
The Airy Technology® R5501 Remote Particle Counter is the most feature-advanced remote particle counter available. Integration is easy into a building automation and cleanroom management system via Ethernet, or (optional) Wireless 802.11 b/g, RS485 or RS232.
The R5501 remote particle counters display and report 6 user-selectable particle size channels, as well as 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.
These remote particle counters store up to 45,000 time stamped particle count and environmental data records which provides data redundancy on every instrument. Airy Technology® counters can be controlled and monitored remotely via web browser.
All Airy Technology® counters meet ISO 21501-4 and JIS B9921. The R5501 ensures compliance with an on-board pulse height analyzer.
