7300 Remote Particle Counter

Model 7300
0.3 – 25 µm @ 1.2 LPM with long-life internal pump & battery
The Particles Plus® 7300 Remote Particle Counter measures 0.3 μm to 25.0 μm with a flow rate of 1.2 LPM and is the most versatile remote particle counter available. The 7300 Particle Counters are purpose-built for ambient and indoor air quality monitoring, industrial hygiene, environmental research, and health & safety applications. Featuring a 1.2 LPM flow rate, the 7300 is optimized for high-concentration environments—providing improved accuracy, reduced coincidence loss, and extended instrument lifespan in comparison to higher-flow models.
The 7300 measures particles from 0.3 to 25 μm in six user-selectable channels, with flexible data reporting formats including mass concentration (μg/m³) and optional corrections for density and refractive index. Integrated sensors for temperature and relative humidity, and optional CO2 and TVOC, offer comprehensive environmental data alongside particle measurements.
With unique features like Particles/Second and the Real-Time Meter, the 7300 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.
Its compact design, durable hardware, and long-life pump allows the 8300 to offer a cost-effective and reliable solution for continuous and remote monitoring. Its standardized architecture and remote diagnostic capabilities reduce maintenance and ensure long-term performance across a wide range of indoor and outdoor air quality applications.
