5.Water Quality Monitoring Station Secondary Water Maintenance

When you use it for the first time or not reuse it for a long time,

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

When using, wash and wipe dry with deionized water (or distilled water) to prevent impurities from being brought into the liquid to be tested.1/3 of the sensor should be inserted into the liquid to be tested.The terminal part should be kept clean and dry.When the sensor is not in use, it should be cleaned.Insert the protective cover with 3.3mol/L KCI solution, or insert the sensor into a container with 3.3mol/L KCI solution.Check whether the terminals are dry.If there are any stains, wipe them with anhydrous alcohol and continue to use them after drying.The sensor should avoid long-term soaking in deionized water, protein solutions, strong acid and alkali solutions, and acid fluoride solutions, and prevent contact with silicone grease.The sensor that has been used for a long time may become translucent or contain deposits.At this time, it can be washed with dilute hydrochloric acid and rinsed with water.When the sensor has a long service life, it can be calibrated and corrected by matching the instrument.When the sensor is maintained and maintained by the above method, it means that the sensor has failed.Please replace the sensor.

Electrodes with conventional conductivity need to be periodically cleaned and calibrated, and the maintenance cycle is determined by the customer according to their working conditions.Conventional electrode cleaning methods: 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 bulbs and reference fluids should be immersed in 3.3 mol/L KCI solution for more than 2 hours.

When using, wash and wipe dry with deionized water (or distilled water) to prevent impurities from being brought into the liquid to be tested.1/3 of the sensor should be inserted into the liquid to be tested.The terminal part should be kept clean and dry.When the sensor is not in use, it should be cleaned.Insert the protective cover with 3.3mol/L KCI solution, or insert the sensor into a container with 3.3mol/L KCI solution.Check whether the terminals are dry.If there are any stains, wipe them with anhydrous alcohol and continue to use them after drying.The sensor should avoid long-term soaking in deionized water, protein solutions, strong acid and alkali solutions, and acid fluoride solutions, and prevent contact with silicone grease.If the platinum sheet of the electrode is stained with grease, you can use degreased cotton to dip acetone or alcohol and gently wipe it clean.If the dirt is insoluble inorganic substances, you can use 30-50% hydrochloric acid to wipe it once a day with clean high-end toilet paper.When the sensor has a long service life, it can be calibrated and corrected by matching the instrument.When the sensor is maintained and maintained by the above method, it means that the sensor has failed.Please replace the sensor.

External surface of dissolved oxygen sensor: Rinse the external surface of the sensor with clean water.If there is still dirt residue,

Please wipe it with a moist soft cloth.For some stubborn dirt, you can add some household detergent solution to the water to clean it.Fluorescent film head surface: If there is dirt on the surface of the fluorescent film head, rinse with clean water or gently wipe with a soft cloth.Pay attention to avoid scratches in the measurement area and affecting the measurement accuracy when cleaning.Avoid sunlight or strong light on the inner surface of the fluorescent film.Do not touch the fluorescent film with your hands or sharp objects.When using it, avoid bubbles attached to the surface of the fluorescent film.

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

Note: Avoid strong vibration damage ring with light-transmitting glass in front of the light-transmitting glass, and do not scratch with hard products.
