How often should I clean the HYDROS 21 sensor?


The cleaning schedule for the CTD (HYDROS 21) will depend primarily on the environment it is being installed in. Installations in sites with the potential for higher biofouling will need more regular cleaning (every two weeks to one month). These sites are typically estuaries, tidal marshes, or areas with higher nutrient loading. Sites with lower biofouling can probably be on a three-month cleaning schedule. These are typically freshwater sites like streams, lakes, etc.
