Thanks to the built-in 1500 mAh battery, it is possible to operate the air humidity meter as a mobile device. As soon as the battery is discharged, it can be recharged via the micro USB interface with a 5 V DC power supply.
The air humidity meter is therefore used, for example, to check the air quality in offices, workshops, school facilities or in logistics to check the premises for volatile organic substances and formaldehyde.
The readings are stored directly on the air humidity meter. A memory with 5000 measuring points is available for the air quality meter. After a measurement, the readings can be analyzed on the air quality meter. In addition, the readings from the air quality meter can be transferred to a PC. When connecting the air quality meter to a PC, the air quality meter is recognized as a mass data storage device. This has the particular advantage that the air quality meter works independently of the operating system. The measured values are saved in CSV file format by the air quality meter.
