Product Description
The PMT® 8503 Handheld Airborne Particle Counter
measures particle sizes from 0.5 to 25.0 μm at a flow rate of 0.1 CFM (2.83 LPM). Featuring the industry’s highest concentration limit of 15,000,000 particles/ft³ at 10% coincidence loss, it is ideal for research, industrial safety, indoor air quality, and cleanroom applications.
The device supports over 10 hours of continuous operation with a lithium-ion battery and introduces the industry’s first sleep and power-saving mode. With its comprehensive self-diagnostics and built-in pulse height analyzer, it ensures maximum reliability.
A color touchscreen display makes operation intuitive. The instrument can display up to 3 user-selectable channels as well as temperature and humidity readings. Thanks to Ethernet, USB, and optional Wireless 802.11 b/g connectivity, the counter integrates seamlessly into cloud and building monitoring systems.
Technical Specification
The PMT® 8503 covers a measurement range of 0.5 to 25.0 μm and operates at a flow rate of 0.1 CFM (2.83 LPM). It is factory-calibrated at 0.5, 1.0, and 5.0 μm and supports up to 3 simultaneous channels. The concentration limits are 15,000,000 particles/ft³ at 10% coincidence loss, validated up to 30,000,000 particles/ft³.
It is powered by a removable lithium-ion battery with more than 10 hours of continuous operation. A 4.3″ color touchscreen display provides easy operation. The internal memory stores 45,000 records, 1,000 sample locations, and 50 recipes.
For data transfer, Ethernet and USB interfaces are standard, with optional Wireless 802.11 b/g. The counter complies with ISO 21501-4, JIS B9921, ISO 14644-1, EU GMP Annex 1, and FS 209E. With its impact-resistant plastic housing, compact dimensions of 13.0 × 10.8 × 31.1 cm, and a weight of only 1.0 kg, it is highly portable. The warranty is 5 years, with 1 year coverage on the vacuum pump.
