1PCS New PF-1 type Fluoride Ion Electrode / Fluoride Ion Selective Electrode
Items Descriptions
1PCS New PF-1 type Fluoride Ion Electrode / Fluoride Ion Selective Electrode
 
PF-1 fluoride ion electrode connector : Q9 screw type
 
Technical index:
1. Measuring range: 10-1 to 106 (mol/dm32. Solution temperature: 5-45 degrees
3. Insulation resistance: ≥1×1011n
|4. Electrode internal resistance: ≤1Mn
5. Zero potential: 0-1PF (electrode pair composed of fluorine electrode and saturated calomel electrode) PREFIX=O use, maintenance and precautions:
1. When measuring the sample and standard solution with the fluoride ion selective electrode, use a magnetic stirrer and make the stirring speed of the sample and standard solution equal.
2. When the fluoride ion selective electrode is used, the battery is composed of saturated calomel electrode in deionized water, and the electromotive force reaches ±320mv before it can be used normally.
3. When measuring the fluoride ion selective electrode, the sample and standard solution should be at the same temperature
4. During the measurement, after the electrode is cleaned with distilled water, it should be dried with filter paper and then tested to prevent measurement errors.
5. When the concentration of the measurement sample is large, it is recommended to use two fluoride ion selective electrodes to avoid errors.
6. The fluorine standard solution is recommended to be stored in a cleaned polyethylene plastic bottle. The volumetric flask, pipette and glass container used should be cleaned in time.
7. After the fluorine electrode is used, it is recommended to clean it with deionized water to 320mv and then dry it. This can extend the service life of the electrode and will not affect the next measurement.
