BQ30 particle measuring device

Air quality monitor for checking the fine particulate and CO₂ burden

Nowadays, the fine particulate burden in the air and its health effects are an essential part of public discussions. But what is it that makes fine particulates so dangerous? Fundamentally, a distinction is made between the two particle fractions PM10 and PM2.5.

Particle measuring device BQ30

PM10 includes all particles with a maximum diameter of 10 µm, and PM2.5 means all particles with a diameter of less than 2.5 µm. These particles are invisible to the naked eye. As small as they are – especially the particles of the size PM2.5 – they can reach the pulmonary alveoli. Yet more minute particles of less than 1 µm can even reach blood vessels.

In our everyday life, we are exposed to countless potential sources of fine particulates. No matter whether you are living or working next to an extremely busy road or near an industrial area – it is likely that the fine particulate burden of your breathing air is increased. In rooms and buildings where many people are situated, the COcontent often increases above average. 

But also ordinary things and tasks such as cooking, vacuuming, candle or tobacco smoke – just like the emissions from heat sources (e.g. stoves and fireplaces) – can have a direct negative effect on the indoor climate and consequently the well-being. For an increased concentration of fine particulates and CO2 in the air can not only affect the overall well-being, but also be responsible for difficulties in concentrating and insomnia as well as for various allergic reactions. On a long-term basis, the exposure to fine particulates increases the risk of developing cardiovascular and respiratory diseases, even pulmonary cancer.

Using the convenient particle measuring device BQ30 you can always keep an eye on the fine particulate, CO, air temperature and humidity values. This way, you can improve the room climate through fresh air supply or the effective use of air cleaners, humidifiers or dehumidifiers whenever required.

A few practical benefits:

  • Long-term air quality monitor for simultaneous detection of particle mass concentration in the air
  • Measurement of fine particulates with a max. diameter of PM2.5 and PM10
  • Indication of CO2pollution, current room temperature and humidity level
  • Memory space for up to 5,000 data sets
  • Bar graph indicator
  • Additional colour indicator display with automatic acoustic alarm for the quick detection of critical particle concentrations
  • Automatic switch-off
  • 3'' colour display for simultaneous indication of all measured parameters 
  • Battery and mains operation possible
  • Adjustable display brightness 
  • Automatically alternating indication of all measured climate parameters
  • Date and time indication
  • Language selection
  • Battery status indication

The compact, long-term air quality monitor BQ30 allows you to simultaneously detect both critical fine particulate concentrations and CO₂ emissions in the air in a reliable and precise way. Additionally, the convenient all-round measuring device also measures the air temperature and humidity level.

Keep an eye on the house dust, fine particulate, soot and pollen concentration

The user-friendly, mobile air quality monitor detects and quantifies the mass concentrations of various fine particulates. For this purpose, the measuring device's laser technology easily captures even the smallest air contaminations of sizes PM2.5 and PM10 in micrograms per cubic metre.

Thanks to the adjustable time intervals, the BQ30 also allows for effective long-term control of the particle burden. Up to 5,000 data records can be saved, including both the PM concentrations and the date of detection. If desired, this large variety of data can be conveniently displayed as curve characteristics on the large 3" colour display.

With respect to the mass concentration of particle size PM2.5 you can define limit values preset in the BQ30 which, when exceeded, trigger an acoustic alarm signal. Additionally, a six-level colour display indicating the respective alarm levels helps you to quickly assess the current state of the particle concentration ranging between good and highly critical.

A human hair has a diameter of approx. 50 to 70 µm. In contrast, the diameter of inhalable dust fractions (PM10) and alveolar dust particles (PM2.5).

All-round measuring device monitoring your feel-good climate

Furthermore, the handy all-round measuring device simultaneously also detects other room climate parameters relevant to health, such as the COburden in ppm, the air temperature ranging from -20 to 70 °C as well as the humidity level of 0 to 100 % RH. The measured PM10 and CO values are displayed on an automatically alternating indication. Another three-colour indicator completes the user-friendly visualization of these two parameters in particular, indicating the air quality on a scale from good to poor. 

Its precise measurement results, wireless and untiring battery operation, low weight and compact dimensions make the air quality monitor BQ30 the perfect companion for wherever a detection of a potentially harmful fine particulate and COpollution is required.

The large 3" colour LCD display of the BQ30 allows you to simultaneously read the particle mass concentration in the air, the CO₂ content, the air temperature, the relative humidity level as well as the date, the current time and the battery status. Moreover, a coloured bargraph indicator reveals at one glance whether the particle burden is in the "green" range.
BQ30 display – good
Displaying different shades of yellow, the air quality monitor BQ30 visually indicates that the measured values for PM10/PM2.5 particles are in the "normal" range. A red display corresponds to a "moderate" contamination. It is also possible to set individual thresholds based on the predefined limit values.
BQ30 display – normal
If the display colour changes to violet or purple, the predefined limit values for the particle quantity have been clearly exceeded. To improve the poor air quality in the short term, proper ventilation may be advisable. Equally, the values for the CO₂ content in the air are also separately displayed with the corresponding colour gradations.
