Environmental Testing Device with data logger / HCHO measurement / battery for mobile use /�2.8 “TFT display / measurement of mass concentration / data storage on SD card
This Environmental Testing Device has many functions. With the Environmental Testing Device 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 Environmental Testing Device can also measure the PM 2.5 and PM 10 mass concentration. The mass concentration of the Environmental Testing Device determines the weight of the particles on one cubic meter.
In addition to particle measurement, the Environmental Testing Device 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 Environmental Testing Device. As a further important property, the Environmental Testing Device can also store data. It is therefore possible with the Environmental Testing Device to evaluate all measured values after a measurement.
