The Airy Technology® H303 Handheld Particle Counter measures 0.3 to 25.0 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 optional temperature and relative humidity. View data on screen or via printer, real time through its versatile output options, or export to Instrument Management Software (IMS). Airy Technology counters can be controlled and monitored remotely via web browser.
All Airy Technology® counters meet ISO 21501-4 and JIS B9921. The H8303 ensures compliance with an on-board pulse height analyzer.
