EC Sensor Preparation
The EC sensor does not need to be soaked or hydrated before use. Use the small brush included in the
probe maintenance kit to clean and loosen any debris before using.
SENSOR INSTALLATION
The HI7698194 can support three different sensors:
Connector 1: pH, pH/ORP
Connector 2: D.O.
Connector 3: EC.
To make installation easier, the sensors have color‑coded caps and the sockets are identified with
colored triangles, corresponding to the colors of the sensors (pH ‑ red; EC ‑ blue; D.O. ‑ white).
