High/Low Water Level Sensor with Dual Probe for Overflow and Dry Running – 120dB Siren & Red Flashing Light, Adjustable Volume, 5m Cable, 9V – for Tanks, Aquariums, Pools, Basements
About this item
- 【5-meter floating sensor】- This alarm has two independent sensors: an overflow sensor above and a dry-running sensor below the normal water level. The floating magnet in the sensor triggers the alarm when the water level changes. You can activate one or both functions as needed for maximum protection against water damage and dry-running pumps.
- 【120dB alarm】- The unmistakable 120dB alarm is accompanied by a conspicuous red flashing light. The volume can be easily increased or decreased by turning a control knob, and can also be muted. DIY tip: The alarm can also be triggered by short-circuiting the two probe wires, making it versatile for integration into your personal security system.
- 【Extendable sensor cable】- The standard 5m sensor cable can be easily extended yourself: simply connect a high-quality copper cable and secure the connection by wrapping it around – this allows you to reach even hard-to-reach places. Please seal/coat the connection point with insulating tape or heat-shrink tubing to make it waterproof. This allows you to extend the cable flexibly according to your needs – and adapt it optimally to your individual installation requirements.
- 【Energy-efficient low-current design】- Operates with a standard 9V block battery (included). Thanks to extremely energy-efficient electronics, the battery has a standby time of over 1 year. A fading alarm tone reliably signals when it is time to change the battery.
- 【Versatile applications】- The ideal protection against water damage and expensive repairs in numerous areas: solar tanks, aquariums, pools, basements, laundry rooms, boiler rooms, or storage rooms. Its robust construction and high alarm volume also make it suitable for commercial applications such as small workshops or horticultural businesses.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.
The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
