our new fine dust measuring instrument you can determine dangerous
particulate pollutions (PM2.5 and PM10), harmful
formaldehyde combinations (HCHO) and organic
combinations (TVOC). For the complete indoor climate
overview the unit has also additional sensors for temperature
and humidity. The hazard assessment is in 3 colors
(green, yellow and red) on the LCD-Display. The device
can be used stationary and mobile especially for personal use.
pollutions PM2.5 and PM10
The fine dust consists of solid and liquid particles. At first
fine dust is released at the source like an exhaust, a new furniture,
..., then it arises by gaseous substances as sulfur. PM10 fine
dust has a maximum diameter of 10 micrometers (µm) and PM2.5
has accordingly a smaller diameter of 2,5 micrometers (µm).
dust is usually generated by human action. Primary fine dust is
caused by emissions from automobile, stoves and heaters…
Another important source is the agriculture for example the ammoniac
emissions from animal keeping.
dust can cause severe health problems. PM10 can penetrate into
the nasal cavities and PM2.5 into the bronchia and pulmonary alveoli.
It can cause allergy symptoms, asthma attacks, respiratory and
ear infections. Lung cancer will caused by cigarette smoke.
Who can be really sure there hides no threat behind the typical
smell of new rooms or new interior fittings? The effect of evaporation
can lead to serious diseases. A formaldehyde measurement gives
are chipboards and glued wood materials such as wallboards. Formaldehyde
can appear in textiles, special insulating materials (foams and
resin), nail polish, cosmetics, cleaning agents and disinfectants,
paints and colors.
threshold value applies for formaldehyde?
Threshold values with an adverse health effect are measured by
„parts per million“ (ppm). This corresponds to a weight
unit milligrams per one kilogram. In textiles is the threshold
value is 16ppm. In interiors the unit is one milliliter per one
cubic meter. Formaldehyde is approved as a preservative and must
be specified in cosmetics if the concentration exceeds 0.05%.
Permitted are 0.1% for oral hygiene articles and 0.5% for nail
Volatile organic compounds (=TVOC) is a group of elements of air
pollutants, which always occur in the ambient air. These are of
natural origin and in commodities of daily use. Interior relevant
sources of emissions are lumber, panels, candles, heating systems,
furniture and furnishings, wall cladding and carpet. Health effects:
tiredness, headache, irritation of eyes, nose, throat etc. Benzene
is a know carcinogenic.
