The UNI-T A25M is a compact, handheld air quality meter designed to measure PM2.5 concentrations with real-time visual indicators. It displays levels using emoticons to quickly represent air quality conditions, making it intuitive and user-friendly for homes, offices, schools, hospitals, and more. PM2.5 is measured across 0–500 μg/m³ with accuracy ranges from ±(10μg/m³+10dgts) to ±(10%+50dgts), while temperature readings (in °C/°F) are for reference only.

With a 520mAh rechargeable polymer battery and wall-mount capability, the A25M is ultra-portable and suited for both mobile and fixed applications. Comes with a 1m micro USB charging cable.
