5501P Remote Particle Counter
Model 5501P
0.5 – 25 µm @ 0.1 CFM with internal pump
The Particles Plus® 5501P 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 5501P 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.
This remote particle counter stores up to 45,000 time stamped particle count and environmental data records which provides data redundancy on every instrument. Particles Plus® counters can be controlled and monitored remotely via web browser.
All Particles Plus® counters meet ISO 21501-4 and JIS B9921. The 5501P ensures compliance with an on-board pulse height analyzer.
