Features: High sensitivity, rapid response time, and accurate reporting. Utilizes photo-electric and transformer isolation for safety and reliability. Integrated sealing design ensures safety and ease of use. Equipped with an isolation layer on the main electrode, it alarms when water reaches a certain level. Auxiliary electrodes are optional to expand the detection range. High/low level alarm signal and multi-relay output modes are available. Ideal for communication base stations, hotels, restaurants, precision computer rooms, libraries, warehouses, alarm centers, or computer room monitoring, and any location requiring water level reporting.
