Model 7501 and 7301 Remote Particle Counters

Brand: Particles Plus, Inc.

The Particles Plus® 7301 and 7501 Remote Particle Counters measure 0.3 or 0.5 to 25.0 μm with a flow rate of 0.1CFM - 2.83LPM.

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 GMP Annex 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 7301 and 7501 can be used as stand-alone battery operated instruments or they 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 7301 and 7501 ensure compliance with an on-board pulse height analyzer.
