With our new mobile fine dust measuring instrument TMT-WP6130 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. If the air quality is bad, the display lights up red and a smiley icon (happy-neutral-sad) appears. If the air quality gets too bad you will be warned by an acoustic signal. The device is equipped with an automatic energy saving mode and switches to standby after 15 minutes and powers off after 120 minutes. The device is especially suitable for personal use.
Particulate 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).
Fine 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.
Fine 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 first insights.
Critical 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.
Which 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 hardener.
Organic compounds TVOC
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.
