Cleaning 

After every use. 

To clean the sensor, perform the following steps: 

 

1. Keep the cables connected to the receptables or us a dummy-connector to keep the receptable pins dry. 
Clean the sensor in cold freshwater. Use a hose to hose off any seawater and salt remnants. Dry off with 
paper towels or leave to dry.   

2. Remove electrode caps and carefully remove the cotton plugs. Rinse with clean fresh water.  

 

3. Use a clean Q-tip soaked in isopropyl alcohol to carefully wipe of the surface of the electrodes. Leave to 
dry and mount new cotton plugs and remount the electrode caps.
