3. Introduction
The HM55 thermo-hygrometer measures and displays room temperature and relative
humidity. You can use the free 'beurer FreshRoom' app (iOS and Android), to upload
®
measured values to your mobile device (via Bluetooth
) for long-term monitoring.
After pairing your mobile device with the thermo-hygrometer, the current time ap-
pears in the LCD Display and then alternates with temperature and the relative
humidity reading.
You can use the app to set high and low thresholds for temperature and humidity. The
LED indicator on the device will then illuminate green or red to indicate that current
readings are within or outside the set range, respectively.
You can connect up to five Thermo-hygrometers using the 'beurer FreshRoom' app
and assign a unique name to each, such as 'kitchen' or 'living room'.
