2501 Remote Airborne Particle Counter

Model 2501

0.5 – 25.0 µm @ 0.1 CFM

The Particles Plus® 2501 Remote Particle Counter is designed for continuous monitoring in cleanrooms and other controlled environments. With four particle size channels ranging from 0.3 or 0.5 up to 25.0 μm, these instruments deliver targeted contamination detection with real-time data collection and configurable alarms for immediate incident reporting and local visual alerts.

The compact, angled enclosures enable installation in tight locations while minimizing disruption to unidirectional airflow. These sensors have four fixed particle size channels and are equipped with an integral critical orifice and flow sensor to provide a stable flow rate from an external vacuum source.

Built for scalability and long-term reliability, these models utilize durable laser diodes backed by a lifetime warranty and deliver exceptional zero-count performance. The 2000 Series sensors allow for efficient particle counting with specifications that exceed the ISO 21501-4 and JIS B9921 calibration standards.

With seamless connectivity, remote diagnostics, and a standardized architecture, they offer simplified integration and a lower total cost of ownership for critical monitoring applications.
