Aurora Multi-Function Air Quality Monitor DM69

The Aurora store offers the Dienmern DM69 for indoor use. Aurora is the storefront; this is the manufacturer’s published model, not an Aurora-designed original. The Dienmern DM69 is a rechargeable indoor air monitor with an LCD. The official specification block confirms an NDIR CO2 sensor (400–5000 ppm) with a switchable 1000 ppm alarm, a laser-scattering PM2.5 sensor (0–999 µg/m³), a Celsius/Fahrenheit switch, and a 3000 mAh battery with a USB charging cable. The introduction also mentions other readings; those are not fully tabulated and are not treated as confirmed specs here. Size and weight are not listed on the page.
