B7300 Benchtop Airborne
Particle Counters
1.2 LPM
The Airy Technology® B7300 Benchtop Particle Counter measures 0.3 μm to 25.0 μm and is 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 B7300 is optimized for highconcentration environments providing improved accuracy, reduced coincidence loss, and extended instrument lifespan in comparison to higher-flow models.
The B7300 measures particles in six user-selectable channels, with flexible data reporting formats including mass concentration (μg/m³) and 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 B7300 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 B7300 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.
