- The Particle Counter KM 3887 measures the concentration of diverse particles in air such as dust, soot, pollen and other aerosol types. The Particle Counter KM 3887 has been designed to detect the exact pollution level in the air. Pollution is usually generated by combustion, material process, manufacturing, energy generation, vehicle emissions and in the building industry. With the help of the Particle Counter KM 3887 you can measure accurately the amount of particulate pollutant in air. You will find high pollution levels in the atmosphere of cities and in the industrial sector which can be measured with this Particle Counter KM 3887. The level of pollution in the air containing unhealthy particles is becoming more important every day, as for instance the soot, which is mainly emitted by industries and vehicles with diesel engines without any special filter. These particle dispersion is responsible for a restricted visibility, the breathe of poison particles and the result of a reduced work performance. These particles can be measured and controlled with the Particle Counter KM 3887. Long ago it is well known that these particles may be one of the causative agents of diseases such as asthma, bronchitis and skin and respiratory diseases (Explanation of some definitions in the measurement of particles). The Particle Counter KM 3887 has been developed for a quick and easy use. It is recommended to be familiar with the Particle Counter KM 3887 as well as with the different weather conditions. Higher fluctuations will depend of the weather conditions. Here you will find another dust particle analyzer to measure simultaneously five particle thickness, air velocity, with memory and RS-232.

- Displays three particle sizes simultaneously on the display. 
- Has a memory for 8000 values. 
- Is powered by a rechargeable accumulator. 
- Meets the ISO 14644-1 standard.
