Water Immersion Sensor
Water immersion sensor for water-accumulation alarms in equipment rooms, telecommunication base stations, warehouses and cabinets. AC detection reduces electrode polarization and sensitivity loss from long-term oxidation. RS485 Modbus RTU, normally-open relay and combined-output versions are available; tap water detection is standard, with pure water detection specified when ordering.
