5301P Remote Particle Counter

Model 5301P

0.3 – 25 µm @ 0.1 CFM with internal pump

The Particles Plus® 5301P Remote Particle Counter measures particles from 0.3 to 25.0 μm at a flow rate of 0.1 CFM (2.83 LPM). These compact and user-friendly instruments display up to six selectable particle size channels, along with optional temperature and relative humidity sensors.

Built for research, industrial hygiene, indoor air quality, and cleanroom applications, the 5000 Series delivers reliable, high-performance monitoring across a wide range of environments. From the cleanest labs to the dirtiest worksites, confidently monitor any environment thanks to the industry’s highest particle concentration limits.

One of the key advantages of the 5000 Series as a remote particle counter is its built-in touchscreen display. It provides real-time visual feedback for technicians working in critical areas, enabling immediate identification of elevated particle counts. Adjustable audible alarms offer an additional layer of awareness in critical environments.

Designed for continuous, powered operation, the 5000 Series is ideal for fixed installations where uninterrupted monitoring is essential. Manage data directly on the device or through the Particles Plus® free software. Export raw data in .CSV or generate custom reports (ISO 14644-1, EU GMP Annex 1, or FS 209E). Remote diagnostics are available through the software from anywhere with an internet connection. The 5000 Series can function as a standalone unit or be seamlessly integrated into building automation and cleanroom management systems.
