The leakage detection sensors SQ4-A21-P and SQ4-A22-P by Panasonic monitor the presence of liquids on a surface. The sensor can be placed underneath pipes to detect liquid leakages. As soon as the sensor optically detects liquid, your Reporter® will notify you through the built-in alarm feature.

The SQ4-A21-P is suited for water leakage detection. The SQ4-A22-P sensor is able to detect Sulfuric acid, Hydrochloric acid, Phosphoric acid, Ammonia, Fluorinert™, Galden®, or Fluorine.

The sensor connects to an adapter that translates the signal for Reporter. All connections are made using the user-friendly M12 connectors. The SQ4 series with Reporter guarantees peace of mind in the easiest plug & play way possible.

Crodeon Cloud

All Reporter's measurements are streamed to the cloud (Crodeon Dashboard) in realtime, where you can view them whenever you want. The Dashboard also features all historical logs. Sensor and Reporter settings like measurement intervals and alarm configuration can be adjusted in the Dashboard as well.

Leak detection sensor with API

Reporter makes every connected sensor API accessible thanks to the user-friendly rest API. This allows for seamless data integration into your own systems or software.
