The Airy Technology® H303 and H503 Handheld Particle Counters measure 0.3 or 0.5 to 25.0 μm with a flow rate of 0.1 CFM (2.83 LPM). Easy to configure, these instruments display up to 3 user-selectable size channels as well as temperature and relative humidity. View data 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 H303 amd H503 ensure compliance with an on-board pulse height analyzer.
