3.6 Maintenance
3.6.1 Clean the sensor
To prevent damage to the sensor, do not use organic solvent solutions (e.g., acetone or methanol) to clean the
sensor. Organic solvents cause damage to the plastic housing and sensor lenses.
Clean the sensor after each deployment to remove unwanted material (e.g., oil, biological growth and
dirt). In addition, clean the sensor before and after calibration.
Adjust the sonde deployment time in accordance with how quickly sensor fouling occurs in the
deployment waters.
1. Clean the sensor with:
• Mild detergent
• Warm water
• Clean, soft toothbrush
• Soft cloth and/or cotton swabs
Note: Do not use dishwashing liquid to clean the sensor. Dishwashing liquid and household cleaners with skin
moisturizer can put a film on the sensor.
2. Rinse the sensor with clean water.
3. Soak the sensor in clean water for a minimum of 30 minutes.
4. Examine the optical windows. If unwanted material is seen on the optical windows, use optical
tissue or a cotton swab with soap and water to clean the optical windows.
5. Rinse the sensor with clean water.
6. If the substance cannot be removed, contact technical support.
