Air Humidity Meter 555BT
With the air humidity meter it is possible to determine the humidity, ambient, wet bulb and dew point temperature. Measurements up to 60 °C are possible with the environmental measuring device. The environmental measuring device can therefore be used universally because of its various measuring functions in order to determine the environmental conditions. With a high accuracy of ± 0.5 °C and ± 3.5% RH. the environmental measuring device determines the current measured value very precisely. The environmental measuring device is used, for example, to check the climatic conditions in offices, cold rooms or in greenhouses.

The air humidity meter with Bluetooth interface can establish a direct connection to an Android or iOS device. This makes it possible to expand the environmental measuring device with a mobile device. With the free “MeterboxPro” app, the measured values ​​from the environmental measuring device can then be displayed in a table or graph on an Android or iOS system. At the same time, they act as data loggers. The recorded measurement data are saved in CSV file format after a measurement.
