• Industry’s highest concentration of 15,000,000 particles/ft3 @ 10% coincidence loss• Ideal for use in research, industrial health and safety, indoor air quality, and cleanroom applications• Up to 10 hours continuous operation on a fully charged battery• Industry’s first Sleep Mode and Power Conservation Mode with Intelligent Battery• The most comprehensive internal self-diagnostics of any handheld particle counter• Real-Time Meter detects particle contamination sources with visual and audible indication• Internet of Things (loT) communication allows for network or cloud-based data options The Particles Plus® 7301 and 7501 Remote Particle Counters measure 0.3 or 0.5 to 25.0μm with a flow rate of 0.1 CFM (2.83 LPM). Easy to configure, thsi instrument displaysup to 6 user-selectable size channels as well as temperature and relative humidity. Viewdata and generate ISO 14644-1, EU GMP Annex 1 or FS 209E reports on screen or viaprinter, 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. Theinstruments’ mass concentration mode approximates density in μg/m3 and allows fordensity and refractive index corrections to ensure accuracy. The 7301 and 7501 can be used as stand-alone battery operated instruments or they canbe easily integrated into a building automation and cleanroom management system viaEthernet, 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 ensurecompliance with an on-board pulse height analyzer.Features and Benefits• 7301: Measures 0.3 μm to 25 μm• 7501: Measures 0.5 μm to 25 μm• 0.1 CFM (2.83 LPM) flow rate• Long life laser diode technology• Measures up to 6 channels of simultaneous data• Approximates mas concentration in μg/m3 with density/refractive index corections• Large easy-to-use icon driven colour touch screen display• Temperature and relative humidity probe included• Stores up to 45,000 sample records, 1,000 sample locations and 50 recipes• Annotation function alows user to save 32 character notations to a sample record• Easy configuration and transferable from instrument to instrument• Connect using Ethernet, USB or (optional) Wireles 802.11b/g, RS485 or RS232• Static or dynamic IP address (DHCP)• Remote diagnostics allows for remote service investigation through the internet• Displays user-definable reports for ISO 14644-1, EU GMP Annex 1 and FS 209E• Internal audible alarm• User-selectable channel sizes• Complies with ISO 21501-4 and JIS B9921 standards• Easy to clean and wipe down with minimal particle traps• Seamless integration into a facitilty monitoring system• Light weight stainles steel enclosure• 2 year limited waranty.
