KM 3887 Particle Counter

Particle counter for measuring particle content in the atmosphere /

counts particles with a thickness of 0.3, 0.5, and 5 µm / RS-232 and software

The KM 3887 particle counter measures the concentration of particles such as dust, soot, pollen, and other aerosols found in the air. The particle counter has been developed to accurately detect the degree of air pollution. Pollution is primarily generated by combustion, material processes, manufacturing, energy production, vehicle emissions, and in the construction industry. With the help of this particle counter, you can measure the precise amount of contaminating particles in the air. You will find high levels of atmospheric pollution especially in cities and the industrial sector. The degree of air pollution with harmful particles, e.g., soot, emitted mainly by industry and vehicles with diesel engines without a special filter, is becoming increasingly important. These dispersed particles are responsible for, among other things, reduced visibility, inhalation of poisonous substances, and therefore reduced work efficiency. It has long been known that particles can be one of the causative agents of diseases such as asthma, bronchitis, skin diseases, and respiratory diseases.

The particle counter has been developed for simple and quick use. It is advisable to familiarize yourself with the instrument and the different atmospheric conditions. It is normal for counts to show greater fluctuations. This depends, for example, on daily changes in atmospheric conditions.

Note trends in particle concentration over extended periods, rather than just differences in measurements taken in succession. The particle counter operates in different modes (single measurement, ISO <C4, continuous, remote, etc.) and displays the result on screen until the device is turned off. The particle counter is very suitable for rapid detection of air contamination levels and is a cost-effective alternative to other measurement methods and much more expensive devices.

- Displays 3 particle sizes simultaneously on screen

- It has a memory for 8000 values

- Powered by a rechargeable battery

- It is valid for making measurements according to ISO 14644-1 standard
