อิเล็กโทรดออกซิเจนละลายน้ำเป็นเครื่องมือตรวจสอบคุณภาพน้ำทั่วไปที่ใช้วัดความเข้มข้นของออกซิเจนละลายในน้ำ. In order to ensure the measuring accuracy and service life of the dissolved oxygen electrode, it is necessary to carry out certain maintenance.

วิธีดูแลรักษาอิเล็กโทรดออกซิเจนละลายน้ำ?

The specific maintenance steps are as follows:

Cleaning the electrode: After each use, the electrode should be cleaned immediately to remove fixtures and dirt on the electrode surface. You can generally clean the electrodes with deionized or purified water, avoiding organic solvents or other chemical agents.

Calibrate electrode: Calibrate electrode regularly to ensure measurement accuracy. Calibration requires the use of standard solution, according to the electrode instruction manual.

Storage electrode: When storing electrodes, keep them away from direct sunlight, อุณหภูมิสูง, or high humidity; มิฉะนั้น, their performance may be affected. Electrodes can usually be stored in a dry, ventilated place and wrapped in a lid or plastic bag to protect the surface from dust and contamination.

Replace the electrode liquid: The electrode liquid is an important factor to maintain the stability and sensitivity of the electrode. Regular replacement of the electrode liquid can ensure the measurement performance of the electrode. When replacing the electrode liquid, follow the operation instructions of the electrode.

Prevent the electrode from drying out: When using the electrode, avoid drying the electrode surface; มิฉะนั้น, the performance of the electrode will be affected. If you do not use the electrode for a long time, place the electrode in a wet cotton cloth or gauze to keep the electrode surface wet.

ในระยะสั้น, in order to ensure the measuring accuracy and service life of the dissolved oxygen electrode, it is necessary to clean, calibrate, store and replace the electrode liquid on a regular basis. นอกจากนี้, in the process of using electrodes, it is necessary to avoid the electrode from being affected by dry, direct sunlight and other adverse environment.
