With our new multi-functional particulate matter detector FS4-G03-300H you can detect and determine dangerous particulate matter pollution (PM2.5) in real time. For the complete living room climate overview, the device also has sensors for temperature and humidity. The risk assessment is shown symbolically in 6 colors (green, yellow, orange ...) on the LCD display. The device can be used both as a stationary and mobile device in homes, offices, etc., but is designed primarily for use in a professional environment and for expert reports.

The compact and handy particulate matter measuring device FS4-G03-300H comes with the complete accessories for wall mounting or as a stand. The matching 230V power supply is also included.




Our professional measuring instrument has an IR LED emitter and a photoelectric triode with scattered light filter for the best results in measurement of fine dust. An automatic calibration function MICOM offers up to nine different calibration points for optimal measurement accuracy in different environments. The air movement required for the measurement is generated by a heat convection initiated in the device. The automatic temperature and humidity compensation for the PM 2.5 measurement is done via an algorithm based on 10 calibration points.

Particulate pollution PM2.5
The fine dust consists of a complex mixture of solid and liquid particles and is divided into different fractions depending on their size. Primary particulate matter is released immediately at the source. If the particles are formed by gaseous precursors such as sulfur and nitrogen oxides and ammonia, they are referred to as secondary particulate matter. Differences are PM10 with a maximum diameter of 10 micrometer (µm) and PM2.5 whose diameter is smaller than 2.5µm.



Fine dust is mostly produced by human action, but can also be of natural origin, for example, as a result of soil erosion. Primary particulate matter is produced by emissions from motor vehicles, power plants and district heating plants, stoves and heaters in residential buildings, in metal and steel production or when handling bulk materials. Another important source is agriculture. Above all, the ammonia emissions from animal contents contribute to secondary fine dust formation.

For years it has been known that particulate matter can cause serious health problems. PM10 can invade the nasal cavity, PM2.5, into the bronchi and alveoli. Depending on the size and penetration depth of the particles, the health effects are different. The effects include the enhancement of allergy symptoms, the increase of asthmatic seizures, respiratory ailments, otitis media and lung cancer caused by cigarette smoke.
