PM2.5 meter UNI-T A25D

PM2.5 meter UNI-T A25D
This product comes with a 3 year warranty. The A25D is an office air quality monitor used for monitoring PM2.5 concentration in homes, shopping centers, offices, stations, etc. PM2.5 particles are air pollutants with a diameter of 2.5 µm or less, containing soot, smoke, metals, nitrates, sulfates, dust, water and tire rubber.
When we breathe in, PM2.5 can get deep into our lungs, and some can even get into our bloodstream. Exposure to fine particles can damage the heart and lungs.

Product parameters:

- real-time measurement of PM2.5 concentration
- measuring temperature and relative humidity
- Built-in LiPol battery
- 3 hours full charge time, can also be used during standard charging,
- PM25 display,
- μg/m³) is exceeded, the backlight glows red
- in addition to exact values and guidance emoticons
