SondeCAM WQ Setup and Operation Selecting a Water Quality Parameter
SondeCAM WQ Setup and Operation
Selecting a Water Quality Parameter
1. Remove the probe guard and port plug from the
bulkhead.
2. Install the pH or dissolved oxygen probe.
3. Insert the magnet (back of screwdriver) into the
bulkhead hole and observe the LED color.
Red = pH Green = DO Hold magnet in bulkhead hole for 30 seconds
until LED color changes to switch modes.

SondeCAM WQ Setup and Operation Calibration
Calibration
Warning: The pH and DO sensors used with the SondeCAM WQ are precise scientific
instruments and care must be taken during calibration in order to ensure accurate readings.
The integrated precision temperature sensor does not require calibration. The depth sensor is calibrated automatically during either pH or dissolved oxygen calibration.
pH Calibration
1. Place the pH probe in pH calibration solution.
Can be done with pH 4, 7, and/or 10 solution. Starting with pH 7 is recommended.
2. Hold magnet in bulkhead hole for 3 seconds until LED
begins to blink red.
3. Remove magnet.
4. Wait for the LED to stop blinking red (about 45 seconds).
There is an automatic retry if the first attempt fails. If the retry fails, the red LED will remain on.
5. Repeat for other calibration solutions. Any un-calibrated points will remain at ideal values.
Note: When handling pH electrodes, rinse the electrodes with distilled water before and after each calibration standard. Blot the end of the electrode with lint-free cloth to remove excess water. Never wipe the electrode to remove excess water – wiping can create static charges that interfere with correct pH measurement.
DO Calibration
1. Expose DO probe to 100% air environment A bag with a wet sponge or paper towel
works well.
In open air the DO value changes frequently
and calibration may fail.
2. Hold magnet in bulkhead hole for 3 seconds until
LED begins to blink green.
3. Wait for the LED to stop blinking green (about 45 seconds).
There is an automatic retry if the first attempt fails. If the retry fails, the green LED will remain on.

Maintenance Water Quality Sensors
Water Quality Sensors
DO Probe (YSI 2002 Galvanic Dissolved Oxygen Sensor)
Preparing for Measurement
1. Remove the probe guard to access the sensor and unscrew from the SondeCAM.
2. Unscrew and discard any old Membrane Cap at the bottom of the electrode.
3. Rinse the internal anode/cathode element with distilled water, blot dry.
4. Fill a new Membrane Cartridge with the provided DO Electrolyte solution.
5. Fill the new Membrane Cap with DO electrolyte and gently tap the edge to release any
trapped air bubbles.
6. Finger-tighten until snug. Do not over tighten.
7. Rinse the assembled electrode with distilled water.
8. Immerse the tip of the electrode in de-ionized water and stir the water for 5 minutes to
properly clean the electrode.
Note: When preparing the sensor, be careful not to touch the membrane with your fingers. The oils on your skin can affect the dissolution of oxygen through the membrane and in turn affect the readings of the sensor.
Sensor Storage
Short Term (1-3 Days) The assembled electrode should be stored in a moist environment, such as in the provided calibration/storage bottle cup or in a beaker of water. When storing in calibration/storage cup, place a small piece of sponge inside. Moisten sponge with distilled or de-ionized water.
Long Term Completely disassemble the electrode. Rinse the anode/ cathode element and Membrane Cap with distilled or de-ionized water. Blot dry all of the parts. The Membrane Cap may be placed on the electrode, but do not tighten. Store all parts securely in the original box.
When ready to use the probe again, follow the instructions in the “Preparing DO Sensors for Measurement” section.
Note: Galvanic DO sensors continually reduce oxygen regardless of if the SondeCAM is powered. This allows for the sensor to report instantaneous measurements when the SondeCAM receives power. As a result, the sensor continues to oxidize even when not in use. The oxidation will result in solids forming and the solution appearing milky white. This is normal and will not interfere with the sensor’s reading unless the buildup becomes excessive.
12
Maintenance Water Quality Sensors
Cleaning and Reconditioning Over time, deposits will develop on the silver anode and gold cathode due to the reduction of oxygen. These deposits are easily removed with 400 grit wet/dry sand paper.
1. Remove the probe guard to access the sensor and unscrew from the SondeCAM.
2. Unscrew and discard the old Membrane Cap at the bottom of the electrode.
3. Rinse the internal anode/cathode element with distilled water, blot dry.
4. Use 400 grit wet/dry sand paper to polish the gold cathode and silver anode.
Gold cathode: Place dampened sand paper face up in your palm. Holding the sensor vertically, bring the gold cathode tip straight down onto the sand paper and twist. The purpose is to remove build-ups and lightly scratch the cathode. The gold should have a matte finish when complete. Silver anode: Place dampened sand paper on tip of sensor, apply light finger pressure, and twist in a circular motion (usually 3-4 twists is sufficient). The purpose is to remove the build-ups without scratching or damaging the anode.
5. After polishing, thoroughly rinse with distilled or de-ionized water and blot dry.
6. Fill the new Membrane Cap with DO electrolyte and gently tap the edge to release any
trapped air bubbles.
7. Finger-tighten until snug. Do not over tighten.
8. Rinse the assembled electrode with distilled water.
Note: When cleaning the sensor, be careful not to touch the membrane with your fingers. The oils on your skin can affect the dissolution of oxygen through the membrane and in turn affect the readings of the sensor.
If the above procedure does not work, please contact FishSens Technology for assistance.

Maintenance Water Quality Sensors
pH Probe (YSI 1001A Amplified pH Sensor)
Preparing for Measurement pH sensors are shipped with the pH bulb moist. Prior to using your WQ-pH for the first time, remove the pH storage bottle from the bottom of the electrode and rinse the electrode with distilled or de-ionized water (Note: Keep the pH storage bottle for late storage). The electrode is now ready for calibration.
Note: When handling pH electrodes, rinse the electrodes with distilled water before and after measuring a sample. Blot the end of the electrode with lint-free cloth to remove excess water. Never wipe the electrode to remove excess water – wiping can create static charges that interfere with correct pH measurement.
Sensor Storage
Short Term Storage Between measurements, store the pH electrode in the pH storage bottle containing pH
4.00 buffer.
Long Term Storage When storing for longer periods, store the pH electrode in the pH storage bottle which came with the electrode. The storage bottle should contain pH 4 buffer.
Do not store the electrode in distilled or deionized water – this will cause ions to leach out of the glass bulb and render your sensor useless. After storage, you may notice white KCl crystals deposited on your electrode. Such salt formation will not interfere with measurements. Simply rinse the electrode with distilled water to remove the crystals and blot dry before use.
Cleaning and Reconditioning As the pH sensor ages, it may exhibit sluggish or noisy readings. Cleaning is recommended when deposits form on the glass and/or platinum surfaces. Try the below procedures in order and stop once good readings are achieved.
Wipe Clean Use a moistened cloth/lens cleaning tissue/cotton swab to remove any contaminants from the probe. Do NOT apply pressure to the glass bulb as it may break.
Wash in Soapy Water
1. Let the probe sit in a solution of liquid soap, (about 1⁄2 teaspoon per 200mL warm
water).
14
Maintenance Water Quality Sensors
2. Using a soft cloth to gently wipe the pH glass – remember that pH glass is extremely
delicate and breaks very easily.
3. Rinse the sensor in clean water when done.
Soak in Hydrochloric Acid
1. Place the probe in one molar (1 M) hydrochloric acid (HCL).
2. Let sit for 30-60 minutes.
3. Rinse in clean water (not DI).
4. Wipe clean with a cotton swab.
5. Re-rinse in clean water.
6. Soak in clean water for an hour. Stir periodically.
Soak the WQ-pH sensor in a beaker of warm water (50°C) for 15 minutes to remove dried gel or salts from the junction. Then place in a beaker of warm 4M KCl solution. Set aside until it returns to room temperature. The gel should be moist and the junction flow should be restored.
Soak in Chlorine Bleach
WARNING: Do not mix the HCL with the chlorine bleach. A toxic gas product can form. Rinse thoroughly before proceeding.
1. Place the probe in 1:1 dilution of commercial chlorine bleach.
2. Let sit for 60 minutes.
3. Rinse in clean water (not DI).
4. Soak in clean water for 60 minutes or more to remove all traces of bleach. Stir
periodically.
5. Re-rinse in clean water.
If the above procedure does not work, please contact FishSens Technology for assistance.
