Airy Technology®
Handheld Particle Counters
H8301-AQM1 and H8301-AQM2
Air Quality Monitors
PM, CO2, Temperature, RH, and TVOC
The Airy Technology® H8301-AQM1 and H8301-AQM2 Handheld Particle Counters were designed for cleanroom monitoring, indoor air quality, industrial hygiene, research, and health & safety applications. Their patented, feature-rich design enables dynamic environmental monitoring and versatile data reporting across multiple industries.
The H8301-AQMs measure particles from 0.3 to 25 μm in six user-selectable channels at a flow rate of 1.2 LPM. They offer data reporting in standard cleanroom formats or by mass concentration in μg/m³, with 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 H8301-AQMs enable efficient, on-the-go particle investigations across nearly any environment. These instruments can also operate as remote particle counters, leveraging their intelligent battery and power conservation modes to achieve up to 100 hours of battery life.
The Airy Technology® standardized hardware and firmware simplify maintenance and reduce the total cost of ownership. Combined with extensive remote diagnostics and a lifetime warranty, the H8301-AQMs ensure industry-leading performance and long-term value.
