This Data Logger / Data Logging Instrument has many functions. With the Data Logger / Data Logging Instrument it is possible to determine the number of particles in the size of 0.3, 2.5 and 10 µm. In addition to measuring the particles, the Data Logger / Data Logging Instrument can also measure the PM 2.5 and PM 10 mass concentration. The mass concentration of the Data Logger / Data Logging Instrument determines the weight of the particles on one cubic meter. In addition to particle measurement, the Data Logger / Data Logging Instrument can also determine the formaldehyde content in ppm. During this HCHO measurement, the temperature, the ambient humidity and the dew point are determined and displayed by the Data Logger / Data Logging Instrument. As a further important property, the Data Logger / Data Logging Instrument can also store data. It is therefore possible with the Data Logger / Data Logging Instrument to evaluate all measured values after a measurement.
