11. Maintenance 11.1 Sensor Care and Maintenance Once the sensors have been properly installed, remember that periodic cleaning and DO membrane changes are required. 11.1.1 DO Sensor For best results, we recommend that the KCl solution and the membrane cap be changed at least once every 30 days. 1. It is important to recognize that oxygen dissolved in the sample is consumed during sensor operation. It is therefore essential that the sample be continuously stirred at the sensor tip.
Maintenance Section 11 with the sample include FEP Teflon, acrylic plastic, EPR rubber, stainless steel, epoxy, polyetherimide and the PVC cable covering. 6. It is possible for the silver anode, which is the entire silver body of the sensor, to become contaminated. This will prevent successful calibration. To restore the anode, refer to Section 11.1.1 DO Sensor, Silver Anode Cleaning. 7. For correct sensor operation, the gold cathode must always be bright.
Section 11 Maintenance Gold Cathode Cleaning For correct sensor operation, the gold cathode must be textured properly. It can become tarnished or plated with silver after extended use. The gold cathode can be cleaned by using the adhesive backed sanding disc and tool provided in the YSI 5238 Probe Reconditioning Kit.
Maintenance Section 11 Probe Sensor Guard Set Screw DO Sensor Hex Key Wrench Figure 11.1 DO Sensor Replacement 4. Insert the new DO sensor module. Make sure that the inside of the probe module sensor port and the o-ring on the sensor are clean, with no contaminants, such as grease, dirt, or hair. The DO sensor is keyed, or has a flat side, so that it cannot be aligned improperly. NOTE: Make sure the DO sensor bottoms out before the set screw is inserted. 5.
Section 11 Maintenance NOTE: The YSI 5563 DO sensor is shipped dry. A shipping membrane was installed to protect the electrode. A new membrane cap must be installed before the first use. Refer to Section 3.4.1 Sensor Installation. 11.1.3 YSI 5564 pH and 5565 Combination pH/ORP Sensor Cleaning Cleaning is required whenever deposits or contaminants appear on the glass and/or platinum surfaces of these sensors or when the response of the sensor becomes slow. 1. Remove the sensor from the probe module. 2.
Maintenance Section 11 1. Soak the sensor for 30-60 minutes in one molar (1 M) hydrochloric acid (HCl). This reagent can be purchased from most distributors. Be sure to follow the safety instructions included with the acid. 2. GENTLY clean the glass bulb and platinum button by rubbing with a cotton swab soaked in the acid. 3. Rinse the sensor in clean water, wipe with a cotton swab saturated with clean water, and then re-rinse with clean water.
Section 11 Maintenance NOTE: In the event that deposits have formed on the electrodes, perform the following additional procedure: 1. Use a mild detergent solution in combination with the brush. Dip the brush in the solution and insert it into each hole 1520 times. 2. Rinse the cell thoroughly in deionized or clean tap water. NOTE: After cleaning, check the response and accuracy of the conductivity cell with a calibration standard.

12. Storage Proper storage between periods of usage will not only extend the life of the sensors, but will also ensure that the unit will be ready to use as quickly as possible in your next application. 12.1 General Recommendations for Short Term Storage No matter what sensors are installed in the instrument, it is important to keep them moist without actually immersing them in liquid. Immersing them could cause some of them to drift or result in a shorter lifetime.
Section 12 Storage dissolved oxygen sensor, with membrane cap still on, in the probe module. 3. Place 1/2″ of water, deionized, distilled or tap, in the transport/calibration cup. CAUTION: The water level has to be low enough so that none of the sensors are actually under water. Check the transport/calibration cup periodically to make certain that the water is still present or the sponge is still moist. 4. Insert the probe module into the cup.
Storage Section 12 2. Seal the empty port with the provided port plug. 3. Place the sensor in the storage vessel (plastic boot or bottle) which was on the sensor at delivery. The vessel should contain a solution which is 2 molar in potassium chloride. NOTE: Make certain that the vessel is sealed to prevent evaporation of the storage solution.
