Remote Particle Counters
Particles Plus Remote Particle Counters
9000 Series
The Particles Plus® 9000 Series Remote Airborne Particle Counters are compact, cost-effective instruments designed for continuous monitoring in cleanrooms and other controlled environments. Wall-mountable and small enough to fit around flow benches, process tools, and tight production spaces, the 9000 Series delivers targeted contamination detection without interfering with critical operations.
With real-time data collection, configurable alarms, local visual alerts, exceptional zero-count performance, remote diagnostics, and seamless integration into cleanroom monitoring systems, the 9000 Series helps lower total cost of ownership while maintaining critical visibility.
To accommodate the wide variety of particle-counting applications, the 9000 Series offers 30 user-selectable particle sizes at no additional cost through the free Particles Plus® software, providing advanced capabilities for specific applications such as troubleshooting, investigations, or future monitoring needs, while preserving the flexibility required for routine monitoring. For 2-channel applications such as pharmaceutical manufacturing, the device can be quickly configured to display and report only the required particle sizes, i.e., ≥ 0.5µm and ≥ 5.0µm channels.

5000 Series
The Particles Plus® 5000 Series Remote Airborne Particle Counters are designed for continuous, powered operation in fixed monitoring locations where uninterrupted particle data is essential. Ideal for cleanrooms, controlled environments, and facility monitoring applications, the 5000 Series combines reliable remote particle counting with the added advantage of a built-in touchscreen display, giving technicians immediate visual feedback directly at the sampling location.
Real-time particle counts, temperature and relative humidity measurements, and adjustable alarms help users quickly identify and respond to elevated contamination events in critical areas. With the built-in Particles Plus® software, remote diagnostics are available from anywhere with an internet connection. Flexible operation as either a standalone unit or an integrated component within building automation and cleanroom management systems, makes the 5000 Series a practical and highly visible solution for continuous contamination monitoring.
