PM2.5 Meter UNI-T A25M

UNI-T A25M
The A25M air quality meter can monitor the concentration of dust particles with a size of 2.5 micrometers. These are particles smaller than 1/20 of the diameter of a human hair that are directly absorbed into the lungs and remain in the atmosphere for a long time. These particles can carry other toxic substances such as heavy metals or dangerous bacteria and viruses. They therefore have a significant impact on human health and air quality.
The A25M is a portable PM2.5 particle meter that can be used in homes, offices, vehicles, laboratories, offices, hotels, schools, factories, conference rooms, airports, hospitals, restaurants, shopping malls and many other public places. It measures the concentration of these particles in micrograms per cubic meter. It displays this concentration in μg/m³ and also in six levels on the backlight LCD display using emoticons. You can turn the white display backlight on or off by briefly pressing the power key. By default, the backlight is automatically turned on when you turn on the device. If the particulate concentration exceeds the standard (PM 2,5> 115μg/m³),
the red backlight turns on. When the particle concentration returns to normal (PM2.5 ≤ 115μg/m³), ​​the red backlight automatically turns off (changes to white). If the PM 2.5> 115μg/m³ particle concentration exceeds a long time, you can turn off the red backlight manually by briefly pressing the power button to save battery power. The display also shows the approximate temperature value.
The device contains a rechargeable polymer battery 520 mAh, which you can charge with the included USB/micro USB cable from a 5V/1A source, which can be, for example, a phone charger.
