Dust Particle Size Analyser KM 3887
Dust particle size analyser of the size of dust particles in the measurement of the amount of particles in the atmosphere / to count particles with a thickness of  0.3, 0.5 and 5 µm / RS-232 and software

The dust particle size analyser KM 3887 measures the concentration of diverse particles in the air such as dust, soot, pollen and other aerosol types. It is designed to detect the exact pollution level of the air. Pollution is usually generated by combustion, material process, manufacturing, energy generation and vehicle emissions. With the help of the dust particle size analyser KM 3887 you can measure accurately the amount of particular pollutant in the air. Pollution levels in the atmosphere of cities and in the industrial sector can be measured with this dust particle size analyser KM 3887. The level of pollution in the air containing unhealthy particles becomes more important every day, for instance, 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 breathing in of poisonous particles and the result of a reduced work performance. The particles can be measured and controlled with the dust particle size analyser KM 3887.  It is well known that these particles may cause such diseases as asthma, bronchitis, skin and respiratory diseases (Explanation of some definitions in the measurement of particles). The dust particle size analyser KM 3887 is developed for quick and easy use. It is recommended to be familiar with the dust particle size analyser KM 3887 in different environments and conditions. Higher fluctuations will depend on the weather conditions. Here you will find another dust particle analyser to measure simultaneously five particle thickness, air velocity, with memory and RS-232. If there are any questions about this dust particle size analyser KM 3887, please have a look at the technical specification below or call: UK customers +44(0) 23 809 870 30 / US customers +1-410-387-7703. Our engineers and technicians will gladly advise you regarding the particle analyzers or any other products in terms of regulation and control, or scales and balances of PCE Instruments.

Taken into consideration the concentration of particles over extended periods of time rather than differences in consecutive measurements, the dust particle size analyser KM 3887 has different operational modes (single measurement, ISO <C4, continuous measurement, remote measurement, etc). The measured result is displayed until the meter is turned off. The dust particle size analyser KM 3887 is suitable for the quick detection of the pollution degree in the air as well as being an affordable alternative to other expensive methods and measuring instruments. Here you will find an overview of all particle analysers (particle counters).

The dust particle size analyser KM 3887 and pollution

Pollution may cause harm to living beings or to the environment. However, pollutant substance should be sufficient enough to cause such environmental damages. This amount can be expressed as the mass of the introduced substance in relation to the mass or volume of the receiving environment and can be measured with the dust particle size analyser KM 3887.
The particles size is not very important for the measurement of pollution, however the number of the particles in the environment is very relevant which can be measured with the dust particle size analyser KM 3887.
Gas pollution are caused by the combustion of fuel and the burning of fuels such as gasoline, garbage, plants and animal waste. With the dust particle size analyser you will be able to determine the number of pollutant particles in the air as well as the level of damage of this air, so the greater the number or dust particles and other pollutant substances, the higher the pollution.
Such pollutant particles can cause respiratory diseases and digestive problems. Therefore, the dust particle size analyser KM 3887 is very important for testing their quality.

If you need another device to detect diverse gas types and to check pollution, you can find it at this link multi-gas detector.

Calibration: Control of the measuring magnitudes correction in relation to measuring instruments without the interference of the measuring system. Also, a determination of the systematic deviation in relation to the real value of the measuring magnitude.

Calibration Certificate: It certifies technical properties of the measuring instruments as well as the possibility of recovering the national standard.

Calibration interval: For exact and permanent measurements, the diverse measuring instruments have to be periodically tested or calibrated. This period of time is called calibration interval. It is almost impossible to determine the calibration period of any measuring instrument. To know the calibration interval it is necessary to consider the following:

- Measuring magnitude and margin of permitted tolerance

- Efficiency of the measuring instruments

- Frequency

- Environmental conditions

- Stability of the previous calibrations

- Required accuracy

- Determination of the company quality assurance

This means that the customer has to be responsible of  establishing and controlling calibration interval. We recommend to establish the calibration interval between 1 and 3 years. We offer to the customer our help to solve problems and technical questions.
