Product Specification

8303 Handheld Particle Counter
The 8303 Handheld Particle Counter measures 0.3 µm to 25.0 µm with a flow rate of 0.1 CFM (2.83 LPM).

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 8303 mass concentration mode approximates density in µg/m³ and allows for density and refractive index corrections to ensure accuracy.

All Particles Plus counters meet ISO 21501-4 and JIS B9921. The 8303 ensures compliance with an on-board pulse height analyzer.
