Bluetooth enabled Beurer sleep line technology uses individually adjustable reference values to indicate indoor air quality.

The digital display shows the current time, relative humidity, timer and temperature in either Celsius or Fahrenheit.

Multiple devices can be viewed in the Beurer FreshRoom app's multi-room display for complete monitoring of your home or office.

Use the wall fastening hook to keep the device secure and visible by your bedside or room entrance.

The low power indicator tells you when it's time to change the batteries.
