Online PH meter is one of the intelligent online chemical analysis instruments, which is widely used in thermal power, chemical fertilizer, metallurgy, environmental protection, pharmacy, biochemistry, food and tap water. PH value or ORP value and temperature Continuous monitoring.

Maintenance of online pH meter electrodes

1. When measuring, it should be washed in distilled water (or deionized water) first, and the water should be absorbed with filter paper to prevent impurities from being brought into the measured liquid. The electrode bulb and liquid junction should be completely immersed in the measured liquid. in liquid.

2. The electrode should be washed when not in use, and inserted into the protective sleeve with 3.5M solution, or the electrode into the container with 3.5M solution.

3. Check whether the terminal is dry. If it is stained, please wipe it with anhydrous alcohol and use it after drying.

4. Long-term immersion in distilled water or protein solution should be avoided, and contact with silicone grease should be avoided.

5. For electrodes that have been used for a long time, their glass membrane may become opaque or have deposits attached. At this time, it can be washed with hydrochloric acid and rinsed with water.

6. It is recommended that the user clean the electrode once a month and calibrate it with the instrument.

7. When you use the above methods to maintain and maintain the electrode, the calibration procedure and normal measurement still cannot be performed, indicating that the electrode has been unable to restore the response, please replace the electrode.

Main Features of Online pH Meter

The water sample cup has anti-fog performance: it can also measure the turbidity of water samples in the rainy season. AC and DC dual-use, easy to carry.

1. It has the function of chromaticity compensation, which compensates the scattered light filtered by the optical lens;

2. The defoaming device of the sensor is avoiding bubble interference;

3. Chinese menu display.

Whether in the biopharmaceutical industry for accurate measurement and high-temperature disinfection, or in the harsh chemical process conditions of high temperature and high pressure and organic solvents, intrinsically safe and explosion-proof applications, we can choose the most suitable online pH meter for you according to the process conditions.
