High sensitivity: as soon as the sensor comes into contact with water, it emits an alarm of 130 dB and will not stop unless turned off or removed from the water, causing constant concern. Easy to install: no complicated installation tools are required. The sensor can be simply installed with double sided tape or screws. Wide range of applications: ideal for bathrooms, laundry rooms, water heaters, sump pumps, sinks, dishwashers, kitchens, warehouses, garages, basements, aquariums, etc. Note: Check the operating status quickly with the ""Set"" button on the side: when pressed, it sounds an alarm; when released, it stops the alarm. In this case, it works normally. Power standard: battery 9V (included) Standby current: 5uAh Sound level: 130dB Inductive cable: approx. 95cm Material: High quality ABS material for the housing Dimensions: 89*55*26mm Package includes: 1 x water alarm Note: No other items are included, colours are based on the first image, the other images show the effect only.
