Smart environmental monitoring solutions
The Particles Plus® 7501 Remote Particle Counter measures 0.5 to 25 μm with a flow rate of 0.1 CFM (2.83 LPM) and is the most versatile remote particle counter available. The 7501 can be used as a stand-alone battery-operated instrument or it can be easily integrated into a building automation and cleanroom management system via Ethernet, or (optional) Wireless 802.11 b/g, RS485, or RS232.
The 7501 reports and displays 6 user-selectable particle size channels, as well as temperature and relative humidity, flow and sensor status, date of the last calibration, serial number, laser on-time, and date of manufacture for easy maintenance and warranty management.
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 data-download software. Particles Plus® counters can be controlled and monitored remotely via a web browser.
The 7501 particle counter stores up to 45,000 time-stamped particle count and environmental data records which provides data redundancy on every instrument. The 7501 also has a mass concentration mode that approximates density in μg/m³.
All Particles Plus® counters meet ISO 21501-4 and JIS B9921. The 7501 ensures compliance with an on-board pulse height analyzer.
