Water Immersion Alarm Detector

Compact unit measuring 9 × 3 × 1.5 cm. Operates on two standard 1.5V AAA batteries (not supplied). Core sensing element is a 24K electroplated detection plate engineered for fast, repeatable response to water exposure. Detects all common household water types: rainwater, municipal tap water, filtered/purified water, laboratory-grade distilled water, and air conditioning condensate. Mounting simplified via 3m double-sided adhesive tape — suitable for horizontal, vertical, or angled surfaces. Alarm volume: 90 dB continuous tone. Activation lasts until the plate dries — no manual intervention needed. Integrated 1-metre lead separates sensor location from alarm housing for flexible deployment in basements, near water heaters, under sinks, or behind washing machines.
