The state-of-the-art data logger enables precise real-time measurement in the range from 0.3 μm to 10 μm to provide a comprehensive picture of the air quality. The results are presented in two units, either in number per m³, number per litre or number per 28.3l. Air sampling is performed by an internal pump. When the particles pass the light source (laser), light scattering occurs; the scattered light is converted into an electrical signal (pulse) by a photoelectric transducer, and the larger the particles, the larger the pulse signal.
The integration of Modbus and MQTT ensures seamless integration into existing networks and enables efficient data communication. The sampling time can be set from 1 to 10 min and the pause time from 1 to 1000 min. This function makes it possible to continuously monitor the cleanliness level and ensure that the premises meet the required standards.
