NOTE
• The dust concentration is displayed from 8 to 999 by
the unit of 1.
• The dust concentration referred to the data sheet of
the sensor manufacturer.
• The dust concentration criteria for the PM1.0 dust
were set based on the same criteria as the PM2.5
dust. (Company standard)
• The dust concentration and level displayed on the
product may differ from other measuring instruments
or other products.
• The displayed dust concentration values can differ
from each other depending on the differences in dust
measuring methods and also from the actual dust
density.
• The dust concentration evaluation is carried out with
our company’s standard test dust.
• If you use a product generating steam or fine particles
(humidifier, cooking appliances, sprays, etc.), the dust
concentration may change.
• The dust concentration may vary depending on the
installation environment and surrounding environment.
• It is also affected by sofas, beds, carpets, vacuum
cleaners, humidity, smoke, bugs, pets, etc.
• It is affected by construction sites, roadsides and
factories.
• Dust concentrations can be measured to be higher
in an environment where external air is introduced,
such as near the entrance, windows and ventilation
openings.
• This is an additional function of the product and may
not work in some products.
• The feature may be changed according to the type of
model.
