Description
UNI-T A25D PM2.5 Monitor
This product comes with a 3-year warranty. The A25D is an office air quality monitor used to monitor PM2.5 concentrations in homes, shopping centres, offices, stations, etc. PM2.5 particles are air pollutants with a diameter of 2.5 µm or less, containing soot, smoke, metals, nitrates, sulphates, dust, water and tyre rubber.
When we breathe, PM2.5 can reach deep into our lungs, and some particles can even enter the bloodstream. Exposure to fine particles can affect the heart and lungs.
Product specifications:
- real-time measurement of PM2.5 concentration
- Temperature and relative humidity measurement
- Built-in LiPo battery
- 3 hours to fully charge; can also be used whilst charging
- PM2.5 display,
- If the limit (μg/m³) is exceeded, the backlight turns red
- In addition to exact values and guidance emojis
