520 * The glass bulb at the front end of the electrode cannot come into contact with hard objects. Any damage and scratches will make the electrode ineffective.
521 * Before measurement, the bubbles in the electrode glass bulb should be shaken off, otherwise it will affect the measurement. When measuring, the electrode should be stirred in the measured solution and then placed still to accelerate the response.
522 * The electrode should be cleaned with deionized water before and after measurement to ensure accuracy.
523 * After long-term use, the pH electrode will become passivated, which is characterized by a decrease in sensitivity gradient, slow response, and inaccurate readings. At this time, the bulb at the bottom of the electrode can be soaked in 0.1M dilute hydrochloric acid for 24 hours (0.1M dilute hydrochloric acid preparation: 9 ml of hydrochloric acid is diluted to 1000 ml with distilled water), and then soaked in 3.3M potassium chloride solution for 24 hours. If the pH electrode is seriously passivated and soaking in 0.1M hydrochloric acid has no effect, the pH electrode bulb can be soaked in 4% HF (hydrofluoric acid) for 3-5 seconds, washed with pure water, and then soaked in 3.3M potassium chloride solution for 24 hours to restore its performance.

730 (1) The equipment itself generally does not require daily maintenance. When an obvious fault occurs, please do not open it and repair it yourself, and contact us as soon as possible.
731 (2) In general, ORP electrodes do not need to be calibrated and can be used directly. When there is doubt about the quality and test results of the ORP electrode, the electrode potential can be checked with an ORP standard solution to determine whether the ORP electrode meets the measurement requirements, and the electrode can be recalibrated or replaced with a new ORP electrode. The frequency of calibration or inspection of the measuring electrode depends on different application conditions (the degree of dirt in the application, the deposition of chemical substances, etc.).
732 (3) There is an appropriate soaking solution in the protective bottle at the front end of the electrode, and the electrode head is soaked in it to ensure the activation of the platinum sheet and the liquid junction. When measuring, loosen the bottle cap, pull out the electrode, and rinse it with pure water before use.

At this time, it should be cleaned with an appropriate solution according to the nature of the contaminant. If the platinum of the electrode is severely contaminated and an oxide film is formed, toothpaste can be applied to the platinum surface and then gently scrubbed to restore the platinum's luster.

759 The fluorescence dissolved oxygen sensor is a newly developed online digital sensor, using imported components and advanced production technology and surface mounting technology.
760
761 It has an IP68 waterproof rating, and the cable is seawater-proof. It can be directly put into the water without a protective tube, ensuring the long-term stability, reliability and accuracy of the sensor.
762
763 The fluorescence dissolved oxygen sensor is based on the principle of quenching active fluorescence by specific substances in physics.
764
765 The blue light from a light-emitting diode (LED) shines on the fluorescent material on the inner surface of the fluorescent cap.
766
767 The fluorescent material on the inner surface is excited and emits red light.
768
769 By detecting the phase difference between the red light and the blue light and comparing it with the internal calibration value, the concentration of oxygen molecules is calculated, and the final value is automatically compensated for temperature and air pressure.

801
802
803 * Sampling: Take representative water samples according to the sampling requirements.
804 * Determine dissolved oxygen in water samples: First rinse the electrode three times with distilled water, then rinse it three times with the water sample, then immerse the electrode in the sample, carefully shake the test cup or stir it to accelerate the electrode balance, let it stand, and record the dissolved oxygen when the reading is stable.
805 * If it is inconvenient to take samples, you can also put the electrode in the measured solution, wait for the measured data to stabilize, read the output data, and take out the electrode after a period of time. Clean it.
806 * After the sample measurement is completed, rinse the electrode three times with distilled water and put the electrode back in the protective solution upright.
807
808 Note: When measuring multiple samples, the electrode should be cleaned before measuring the next sample to avoid affecting the experimental data.
809
810 If the water conditions are complex and you want accurate data, you need to wipe the sensor probe frequently.

816 * To ensure that the electrode measures correctly on the pipeline, avoid bubbles between the measuring cells that may cause data inaccuracy.
817 * Please check whether the packaging is intact and whether the product model is consistent with the selected model.
818 * Do not connect the wires with power on. After the wiring is completed and checked, power can be turned on.
819 * Do not arbitrarily change the components or wires that have been welded at the factory when using the product.
820 * The sensor is a precision device. When using it, please do not disassemble it by yourself or contact the sensor surface with sharp objects or corrosive liquids to avoid damaging the product.

828 It has an IP68 waterproof rating, and the cable is seawater-proof.It can be directly put into the water without a protective tube, ensuring the long-term stability, reliability and accuracy of the sensor. This sensor probe uses a scattered light turbidity measurement method.
829
830 Since the turbidity in the water sample causes light to scatter, the intensity of the scattered light in the direction perpendicular to the incident light is measured and compared with the internal calibration value to calculate the turbidity in the water sample.
