8503 Handheld Particle Counter measures 0.5 to 25.0 μm with a flow rate of 0.1 CFM (2.83 LPM).
Model 8503
0.5 µm – 25 @ 0.1 CFM
The Particles Plus® 8503 Handheld Particle Counter measures 0.5 to 25 µm with a flow rate of 0.1 CFM (2.83 LPM) and can display up to 3 particle size channels as well as (optional) temperature and humidity data.
Easy to configure, this instrument displays up to 3 user-selectable size channels as well as (optional) temperature and relative humidity. View data and generate ISO 14644-1, EU GMP Annex 1 or FS 209E reports. Export to Particles Plus® data-software. The 8503 also has a mass concentration mode that approximates density in μg/m³.
All Particles Plus® counters meet ISO 21501-4 and JIS B9921. The 8503 ensures compliance with an on-board pulse height analyzer.
