5. Online Turbidity Analyzer Maintenance

When using for the first time or after a long period of disuse,

The pH sensitive bulb and reference junction should be immersed in 3.3 mol/L KCl solution for more than 2 hours.

When using, it should be washed with deionized water (or distilled water) and wiped dry to prevent impurities from entering the measured liquid. 1/3 of the sensor should be inserted into the measured liquid. The terminal part should be kept clean and dry. The sensor should be cleaned when not in use, and inserted into a protective cover with 3.3mol/L KCI solution, or the sensor should be inserted into a container with 3.3mol/L KCI solution. Check whether the terminal is dry. If there are stains, please wipe it with anhydrous alcohol and continue to use it after drying. The sensor should avoid being immersed in deionized water, protein solution, strong acid and alkali solution, and acid fluoride solution for a long time, and prevent contact with silicone grease. The glass membrane of the sensor that has been used for a long time may become translucent or have sediment. At this time, it can be washed with dilute hydrochloric acid and rinsed with water. When the sensor has been used for a long time and measurement errors occur, it can be calibrated and corrected by cooperating with the instrument. When the above methods are used to maintain and service the sensor and still cannot be calibrated and measured, it means that the sensor has failed. Please replace the sensor.

Conventional conductivity electrodes need to be cleaned and calibrated periodically. The maintenance cycle is determined by the customer based on their working conditions. Conventional electrode cleaning method: Use a soft brush to remove attachments (be careful to avoid scratching the electrode surface), then clean with distilled water, and then perform calibration operations.

The ORP sensitive bulb and reference junction should be immersed in 3.3 mol/L KCl solution for more than 2 hours.

When using, it should be washed with deionized water (or distilled water) and wiped dry to prevent impurities from entering the measured liquid. 1/3 of the sensor should be inserted into the measured liquid. The terminal part should be kept clean and dry. The sensor should be cleaned when not in use, and inserted into a protective cover with 3.3mol/L KCI solution, or the sensor should be inserted into a container with 3.3mol/L KCI solution. Check whether the terminal is dry. If there are stains, please wipe it with anhydrous alcohol and continue to use it after drying. The sensor should avoid being immersed in deionized water, protein solution, strong acid and alkali solution, and acid fluoride solution for a long time, and prevent contact with organic silicone grease. If the platinum sheet of the electrode is stained with grease, it can be gently wiped clean with absorbent cotton dipped in acetone or alcohol. If the contamination is an insoluble inorganic substance, it can be scrubbed with 30-50% hydrochloric acid. It can also be wiped once a day with clean high-grade toilet paper. When the sensor has been used for a long time and measurement errors occur, it can be calibrated and corrected by using the instrument. If the sensor cannot be calibrated and measured after the above maintenance and care, it means that the sensor has failed. Please replace the sensor.

Dissolved oxygen sensor outer surface: Rinse the outer surface of the sensor with clean water. If there is still dirt remaining,

Please wipe with a damp soft cloth. For some stubborn dirt, you can add some household detergent to the water to clean it. Fluorescent membrane head surface: If there is dirt on the surface of the fluorescent membrane head, please rinse it with clean water or wipe it gently with a soft cloth. Pay attention to the strength when cleaning to avoid scratching the measuring area and affecting the measurement accuracy. Avoid the inner surface of the fluorescent membrane from being exposed to sunlight or strong light. Do not touch the fluorescent membrane with your hands or sharp objects. Avoid bubbles on the surface of the fluorescent membrane when using it.

Turbidity sensor maintenance: If the sensor needs to be cleaned, it can be cleaned with warm water and an appropriate amount of detergent.

Note: Avoid strong vibrations that damage the front transparent glass, and do not scratch it with hard objects.
