Model 9300P

0.3 – 25.0 µm @ 1.2 LPM

The Particles Plus® 9300P 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 up to 25.0 μm and a quiet 1.2 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 9300P features onboard storage for redundant data validation and secure user access. The compact, angled enclosure enables 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 thry deliver exceptional zero-count performance. With seamless connectivity, remote diagnostics, and a standardized architecture, the Particles Plus® 9300P offers simplified integration and a lower total cost of ownership for critical monitoring applications.
