Home water-level alarm that warns of both overflow and low-water conditions using dual probes and visible audio alerts.

Will it give dependable alerts where you need them most?

⚡ At a Glance
  • Detection Capability: Dual-probe high and low water detection with magnetic float switching, includes 16.4 ft detection cord and extendable line up to 164 ft (50 m)
  • Best for: Homeowners, smallholdings and facilities needing unattended water-level monitoring
  • Not ideal for: Situations requiring certified industrial-grade waterproofing beyond IP55

Dual float probes use magnetic induction to register high or low water events. Solar charging and USB DC backup keep the rechargeable battery topped up for extended standby.


Months without battery swaps - with the upgraded solar charging design

High-conversion solar panel charges an integrated rechargeable lithium battery and a USB DC charging cable is supplied for indoor charging. The unit meets IP55 rainproof and dustproof standards to allow outdoor placement.

Long standby periods reduce maintenance, with around three months of standby after a full charge, and USB charging as a convenient backup.

Clear high and low alerts - with dual probe float detection

Two floating probes detect overflow and water shortage through magnetic induction; reversing the float ball changes detection mode and the overflow probe mounts above the normal water line while the low probe remains submerged.

Selectable high or low alarms let users prevent overflow or dry-run scenarios, useful for tanks, basements and aquaculture setups.

Audible and visible warnings for quick response - with a 129 dB red strobe siren and adjustable volume

A 129 dB siren pairs with a red strobe light and volume can be changed by briefly pressing the power switch; the alarm can also connect into a home security arrangement.

Loud sound and a flashing strobe ensure alerts are noticed at night or across larger properties, giving time to act before damage occurs.
