climate in the apartment or should it be better aired?
air quality monitor LQ1-CO2-B530 reliably and
precisely measures the indoor air quality.
Indoor air quality, often referred as a feel-good climate,
is the core of demand-driven ventilation and is determined by
the factors CO2 and VOC content as well as
relative humidity and temperature.
The compact and handy air quality monitor LQ1-CO2-B530
reliably and precisely measures your indoor air quality. With
a good indoor air quality, humans, animals and plants feel most
comfortable. Bad air quality in homes or offices, on the other
hand, causes headaches, fatigue and discomfort. A look at the
display is enough and the cause quickly is determined, maybe
it is too much used air, too low or too high humidity or a too
high VOC load. For a quick check, the room air quality is signaled
by means of three LED backlights green
(good room air climate) / yellow (sufficient
room air climate) / red (bad room air climate).
professional meters have two separate IAQ sensors NDIR
and VOC for measuring carbon dioxide (CO2)
and mixed gas / air quality (VOC). Many low-cost
manufacturers use "combined sensors", but a NDIR-CO2
meter measures selectively and can not detect VOCs, a VOC mixed
gas sensor can not detect oxides and therefore no CO2 molecules.
Here, an attempt is made to derive one measurand from the other,
but both measurands are not interconvertible or there are no
universally valid derivatives to each other.
compact and handy air quality monitor LQ1-CO2-B530
comes with the complete accessories for wall mounting or as
a display stand. The matching 230V power supply is also included.
Our devices have the 2 necessary separate IAQ sensors
NDIR and VOC for the detection of both gas groups.
From this and from the temperature and humidity values, the
absolute air quality is calculated..
about absolute air quality:
Normally most people spend more than 20 hours a day in various
indoor areas, drinking about 2.9 liters of fluid and eating
1.3 kg of food. Up to the current fine dust and air quality
discussion little attention is paid to this circumstances although
humans inhale daily about 15kg of air.
determine the absolute air quality of interiors,
complex analytical methods and measuring instruments
subjective air quality impressions are
simply wrong due to the habituation effect, because
those who spend more time in a poorly ventilated room usually
assess air quality better than they would when entering the
room. In addition to the directly perceptible odor-active substances,
however, there are also odorless air fractions, e.g.
the VOCs (Volatile Organic Compounds) this means volatile
mixed gases. The sources of emissions can be found everywhere
in the household. Every piece of furniture, every carpet,
every curtain releases permanent pollutants. When cleaning
or cooking in the apartment also various VOCs are emitted. Even
the pure presence of humans and animals leads to the release
of volatile mixed gases and CO2 and thus to the reduction of
