Aurora 8-in-1 Particle and Gas Monitor DM306B

The Aurora store offers the Dienmern DM306B for indoor use. Aurora is the storefront; this is the manufacturer’s published model, not an Aurora-designed original. The Dienmern DM306B shares the 90 × 90 × 50 mm cube housing with the DM306C but measures particles and gases instead of carbon dioxide. It displays PM2.5, PM10, PM1.0, formaldehyde, TVOC, temperature, humidity, and an AQI indication, with a laser-scattering particle sensor and a semiconductor HCHO/TVOC sensor. A 2000 mAh battery charges over Type-C. Use it to watch dust and odor-related changes in a room; it is not a CO2 meter and not a medical or life-safety alarm.

Best for

Desk or countertop monitoring where particle and VOC/formaldehyde trends matter, such as a living room or a recently furnished space. Not a CO2 ventilation monitor.
