Anderaa 5819 Conductivity Sensor
Sensor Maintenance
Maintenance must be conducted regularly to ensure the function and accuracy of the sensor.
| Maintenance frequency | Description |
|---|---|
| Every Two Weeks | Visually check the sensor for fouling or organic buildup. Clean with a damp cloth, if fouling cannot be removed by this method progress with the monthly cleaning regime noted below. |
| Monthly | The ceramic hosing will tolerate most cleaning agents. Often 30% Hydrochloric acid (HCL) (Muriatic acid) will be useful for removing barnacles and similar fouling. We also recommend using repair lack on any scratches since this can affect the accuracy by making a shortcut for the seawater loop. Fouling consisting of calcareous organisms (e.g. barnacles), can be dissolved by dipping the sensor/instrument in a weak acid solution (e.g. 7% Vinegar). |
Sensor Calibration
Calibration should be conducted by an Aanderaa certified calibration laboratory. Please contact GroAqua Support to arrange calibration.
| Calibration frequency | Description |
|---|---|
| Annual | Annual recalibration is optimal and recommended by the factory, although for many applications this may not be possible. In case where longer calibration intervals are expected use of a controlled reference can be adequate to QC the data - contact GroAqua for further assistance with controlled reference. |
Fault Finding
Check K-Mote is on, if LED is not flashing, follow the diagnostics steps on the K-Mote sensor diagnostics page.
| Fault | Possible Issues | Solution |
|---|---|---|
| Erratic sensor readings | Fouling buildup on sensor | Visually inspect sensor and clean as per the above cleaning methods. Consider applying anti fouling paint (contact Insert Aanderaa email here for further information) |
| Inaccuracy of readings | Damage from cleaning or removing barnacles/organic matter | Use repair lack on scratches etc |
| No sensor readings | Power supply issues, cable/connector may be disconnected or damaged | Inspect sensor cable for damage, inspect connectors on K-Mote to ensure securely plugged in, inspect K-Mote power supply to ensure no damage has occurred. Ensure solar panel (if using) is orientated for optimal sun exposure and clean if necessary. Ensure K-Mote antenna is installed properly and the K-Mote is switched on. |
