8306 Handheld Particle Counter
Model 8306
0.3 – 25 µm @ 0.1 CFM
The Particles Plus® 8306 Handheld Particle Counter is designed for cleanroom monitoring, indoor air quality, industrial hygiene, research, and health & safety applications. Its patented, feature-rich design enables dynamic environmental monitoring and versatile data reporting across multiple industries.
The 8306 measures particles from 0.3 to 25 μm in six user-selectable channels at a flow rate of 0.1 CFM (2.83 LPM). It offers data reporting in standard cleanroom formats or by mass concentration in μg/m³, with optional density and refractive index corrections. Included temperature and relative humidity probes, along with optional CO2 and TVOC sensors, provide comprehensive environmental monitoring.
With unique features like Particles/Second and the Real-Time Meter, the 8000 Series enables efficient, on-the-go particle investigations across nearly any environment. The instrument can also operate as a remote particle counter, leveraging its intelligent battery and power conservation modes to achieve up to 100 hours of battery life.
The Particles Plus® standardized hardware and firmware simplify maintenance and reduce the total cost of ownership. Combined with extensive remote diagnostics and a lifetime warranty, the 8306 ensures industry-leading performance and long-term value.
