instructions for industrial electrodes br


br

Industrial pH electrodes adopt circular polytetrafluoroethylene liquid interface, gel electrolyte and special glass sensitive membrane. Fast response and stable. This kind of material belongs to inorganic material with good qualitative performance, and its performance has reached the international level. In all possible links, petrochemical materials will be replaced with renewable and sustainable materials of the same kind of electrode. BR, Br

performance characteristics BR, Br

1. It is easy to use without adding electrolyte. BR, Br

2. Gel electrolyte salt bridge can effectively prevent electrode poisoning, such as s2-, CN ions. BR, Br

3. The use of antifouling annular polytetrafluoroethylene liquid interface is not easy to block, but the value of waste pulp made in overseas bases of other countries is becoming increasingly prominent for long-term testing. BR, Br

4. Different electrode sensitive membranes are used for pH measurement under various conditions. The electrode has low internal resistance, fast response and good stability. BR, Br

scope of application BR, Br

1. The electrode can be used with various acidity meters. "Br", "br"

2. The electrode adopts the terminal mode and is equipped with standard 3/4 inch thread. BR, Br

3. If the electrode is normally used for one year, the service life of the electrode will be shortened due to poor environment or improper maintenance. BR, Br

Maintenance BR, Br

1. When measuring, wash it in distilled water (or deionized water) first, and suck the water dry with filter paper to prevent impurities from being brought into the measured liquid. The electrode bulb and liquid complex are immersed in the measured liquid when applied. Br> br

2. Common electrical faults: when loading, it should be cleaned when it is not in use. Insert the protective sleeve with 3.5m potassium chloride solution, or insert the electrode into the container with 3.5m potassium chloride solution. BR, Br

3. Check whether the wiring terminal is dry. If there is any dirt, please wipe it with absolute alcohol and use it after drying. BR, Br

4. Avoid long-term immersion in distilled water or protein solution, and prevent contact with silicone grease. BR, Br

5. The glass film of the electrode that has been used for a long time may become translucent or attached with sediment. At this time, it can be washed with dilute hydrochloric acid and washed with water. BR, Br

6. It is recommended that users clean the electrode once a week and coordinate with the calibration of the instrument. BR, Br

7. When you use the step-by-step method to maintain and maintain the electrode, the calibration procedure and normal measurement still cannot be carried out, indicating that the electrode has failed to recover its response. Please pound the electrode more. BR, Br
