Product description
UNI-T A25D is an air quality meter that analyses the concentration
of PM2.5 particles in the air.
PM2.5
(PM stands for particulate matter)
with a diameter of 2.5 micrometres or less. When particles of this
kind are inhaled, they can make their way deep into the lungs,
where they can pass into the bloodstream. The causes of high
levels of PM2.5 can be natural or man-made. Common sources of
these particles are emissions from fires and vehicles. Exposure to
these particles in high concentrations can be detrimental to health.
