1. The probe is made of high-quality stainless steel material, which can effectively prevent rust and accurately detect the water, with high sensitivity and long service lif.<br>2. Compact and convenient, flexible to install.<br>3. The water leakage detection electrode is exquisite and small, and can be flexibly installed in a narrow corner for monitoring the water level of the ground or a limited height water level space.<br>4. Detection principle: When the two probes of the detection electrode touch the water together, the alarm signal is transmitted to the sensor and the alarm is driven.<br>5. Widely used: residential, shopping malls, companies, factories, warehouses,bathrooms, kitchens.<br><br>Note: The water leakage detection probe is just a detection probe, which is the last two metal contacts. There is no circuit inside. It cannot be used alone. It needs to be used with the detection alarm host. When the detection probe touches water, the two wires short-circuit. When there is no water, it is normally open. Reliable performance and easy installation.<br>Due to different batches, there may be differences in product appearance and printed text, which not affect use.<br>Specifications:3 Meter Cable<br>Color:White<br>Material:ABS<br><br>Package Contents:<br>1 * Wired Type Water Leakage Alarm<br><br>Only the above package content, other products are not included.<br>Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
