Model 7501
0.5 – 25 µm @ 0.1 CFM with long-life internal pump & battery
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 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 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.
