Malem™ bedwetting alarm (MO3) - Single sound

This body-worn alarm by Malem is always a popular choice. This is the lightest and smallest bedwetting alarm available. It weights just 24g including batteries and measures 49 x 39 x 18mm. 

This alarm is comfortably worn on the nightwear close to the shoulder. After being woken up over several nights, the child will either wake up before they do a wee or will learn to sleep through the night without wetting the bed. 

The Malem MO3 features a loud single tone which sounds continuously until the sensor is removed, allowing sufficient time to effectively respond to the alarm. A flashing glow is emitted when the alarm is sounding.
