The patented, moulded plastic Urosensor™ is easy to clean and dry for instant re-use and it goes right inside the underpants to instantly detect the first drops of urine. There are no metal contacts and the Urosensor™ will not corrode or deteriorate in urine.
The Urosensor™ is a consumable item because the battery cannot be replaced due to the unit being permanently sealed to prevent moisture entering the electronics. However, the long life battery together with special battery saving technology means that the Urosensor™ will not need to be replaced during a normal treatment period. It will last at least a year used every night, provided the alarm is turned off when it is not in use. (The reason most other wireless alarms have a separate transmitter is because the sensors cannot be sealed due to inadequate battery life. The battery in many wireless alarms has to be changed regularly, often at monthly intervals).
