The PCE-PCO 1 dust meter is a versatile measuring device for capturing particle concentration in the air. It can measure six different particle sizes and is equipped with sensors for temperature and relative humidity, making it a true all-rounder. The built-in camera allows for the connection of measurement data with image and video material. The dust meter is designed to accurately determine the level of air pollution, primarily caused by combustion, manufacturing, energy production, vehicle emissions, and industry. With the help of the dust meter, the exact amount of dirt particles in the air can be measured. A high level of pollution is particularly found in urban areas and work environments. The pollution level of the air with harmful particles, such as soot emitted by industry and especially by diesel vehicles without special filtration, is becoming increasingly significant. Such dispersed particles are responsible for reduced visibility, the spread of contaminants, inhalation of toxic substances, and thus reduced work productivity. It has long been known that these particles also contribute significantly to many medical conditions, such as asthma, bronchitis, as well as skin and lung diseases.
