Reference-Grade Air Quality Station
A reference-class air-quality station combining meteorological measurement with continuous monitoring of PM₁/₂.₅/₁₀, O₃, NO₂, SO₂ and CO. Designed for civic monitoring networks and regulatory reporting.

The OWAQ3000 is the reference-class node in the OWS air-quality range — a single station that pairs survey-grade meteorology with continuous gas and particulate monitoring. Built to anchor civic air-quality networks where the readings have to stand up to regulatory scrutiny.
Solar-autonomous, IP66, and field-serviceable; the same chassis hosts the mini and home nodes downstream, so a mixed-density rollout shares a common parts catalog.
