b'SensorSpecific Advice for LongTerm StorageConductivity Dissolved OxygenMany field conductivity sensors have internalOptical and electrochemical dissolved oxygen electrodes, and those need to be cleaned priorsensors have different long-term storage to storage. Insert a conductivity brush into therequirements. For both sensor types, ensurechannel leading to the electrode and sweepthat the probes are clean. 15 to 20 times. You can use soap and water to clean the electrodes if deposits have formed.Optical sensors have a sensor cap that needs to stay hydrated throughout storage. The best way Conductivity sensors can be stored dryto do this is to install the shipping cap with a wet long-term. Some EXO sondes use Wipedsponge over the sensor cap. Check the sponge Conductivity sensors, which have exposedperiodically to ensure it is still hydrated. If you no electrodes. Those electrodes can be cleanedlonger have the cap and sponge, the sensor can using a soft brush, soap, and water. The Wipedbe stored in a beaker full of clean tap or DI water. Conductivity sensor can also be stored dry. Be sure to change the water out monthly. For electrochemical DO sensors, remove the sensor cap, then clean and dry the electrode. ConductivityInstall a new, dry sensor cap to protect the Brush electrode, and store the sensor dry. pH and pH/ORP DIWaterFor pH and pH/ORP sensors, ensure the sensor is clean and free of debris. Remove the sensor from the instrument, and store the sensing endOptical Sensorsin the bottle the sensor was shipped in. If the storage solution that originally came withOptical sensors with glass faces, like turbidity, the sensor is gone, you can use pH buffer 4. DoTotal Algae, fDOM, and Rhodamine WT, are not store pH and pH/ORP sensors in DI water orrelatively low maintenance. Prior to long-term tap water with low conductivity. Doing so canstorage, ensure the sensor bodies are clean and damage the sensor.wipe the sensor face with a lint-free cloth.These sensors can be stored dry.Storage For instrument-specific storage instructions, Bottle please refer to the appropriate user manual.Questions about instrument storage?For anything YSI instrument-related, contact our technical support team atinfo@ysi.com or +1 (937) 767-2762.
