7501-30 Large Particle Counter

Model 7501-30

0.5 – 75 µm @ 0.1 CFM with long-life internal pump & battery

The Particles Plus® 7501-30 Remote Particle Counter measures 0.5 to 75.0 µm with a flow rate of 0.1 CFM (2.83 LPM). Easy to configure, this instrument displays up to 6 user-selectable size channels as well as temperature and relative humidity. View data and generate ISO 14644-1, EU GMPAnnex 1 or FS 209E reports on screen or via printer, USB key, real time through its versatile output options or export to Particles Plus® Instrument Management Software. Particles Plus® counters can be controlled and monitored remotely via web browser. The instruments’ mass concentration mode approximates density in µg/m3 and allows for density and refractive index corrections to ensure accuracy.

The 7501-30 can be used as stand-alone battery operated instruments or it can be easily integrated into a building automation and cleanroom management system via Ethernet, USB, or (optional) Wireless 802.11 b/g, RS485 or RS232.

All Particles Plus® counters meet ISO 21501-4 and JIS B9921. The 7501-30 ensures compliance with an on-board pulse height analyzer.
