R306P and R506P Remote Particle Counters

R306P and R506P Remote Airborne Particle Counters
0.1 CFM (2.83 LPM)
- Industry’s highest concentration of 15,000,000 particles/ft³ @ 10% coincidence loss
- Ideal for use in Cleanrooms, Industrial Health & Safety, and Air Quality applications
- Unparalleled and most comprehensive internal self-diagnostics of any remote particle counter
- Remote diagnostics allows for remote service investigation through the Internet
- Supports MODBUS TCP, RTU & ASCII communication over Ethernet, or (optional) RS-485/RS-232
- Internet of Things (JSON) communication allows for network or cloud based data options
The Airy Technology® R306P and R506P Remote Particle Counters measure 0.3 or 0.5 to 25.0 μm with a flow rate of 0.1 CFM (2.83 LPM) from an internal vacuum pump and are the most feature-advanced remote particle counters 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 R306P and R506P remote particle counters display and report 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.
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 R-306P and R-506P ensure compliance with an on-board pulse height analyzer.
