H303 and H503 Handheld Particle Counters

H303 and H503 Handheld Airborne Particle Counters

0.1 CFM (2.83 LPM)

Industry’s highest concentration of 15,000,000 particles/ft³ @ 10% coincidence loss
Ideal for use in Cleanrooms, Industrial Health & Safety, and Air Quality applications
>10 hours continuous operation on a fully charged battery
Industry’s first Sleep Mode and Power Conservation Mode with intelligent battery
Unparalleled and most comprehensive internal self-diagnostics of any remote particle counter
Internet of Things (JSON) communication allows for network or cloud based data options

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.
