9301P Remote Airborne Particle Counter
Particles Plus Remote Particle Counters
Model 9301P
0.3 – 25.0 µm @ 0.1 CFM
The Particles Plus® 9301P Remote Particle Counters are designed for continuous monitoring in cleanrooms and other controlled environments. With 30 user-selectable particle size channels ranging from 0.3 or 0.5 up to 25.0 μm and a quiet 0.1 CFM (2.83 LPM) internal pump, these instruments deliver targeted contamination detection with real-time data collection, and configurable alarms for immediate incident reporting and local visual alerts.
Calibrated to ISO 21501-4 standards for traceability, the 9301P features onboard storage for redundant data validation and secure user access. The compact, angled enclosures enable installation in tight locations while minimizing disruption to unidirectional airflow.
Built for scalability and long-term reliability, these models utilize durable laser diodes backed by a lifetime warranty, and deliver exceptional zero-count performance. With seamless connectivity, remote diagnostics, and a standardized architecture, they offer simplified integration and a lower total cost of ownership for critical monitoring applications.
