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