Specifications

Features:

  1. The measuring range:  10¯1 to  10 ¯6 (mol/dm3
2. The solution temperature: 5-45 degrees
3. The insulation resistance: 1 x 1011 or more studying
4. The electrode resistance: 1 m or less studying
5. Zero potential: 0-1 pf (composed of fluorine electrode and saturated calomel electrode electrode pairs)

  1. The fluoride ion selective electrode in the determination of sample and standard solution, the application of magnetic stirrer, and make the sample and standard solution stirring rate are equal.
2. The fluoride ion selective electrode used in deionized water and saturated calomel electrode of the battery, electromotive force can be normal use after up to + 320 mv.
3. When fluorine ion selective electrode determination, sample and standard solution should be in the same temperature
4. In the measurement, the electrode with distilled water after cleaning, apply after dry filter paper test, in order to prevent the cause measurement error.
5. Large difference in the measurement sample more concentration, suggested two fluorine ion selective electrode, lest cause error.
6. Fluoride liquid standard recommendation in poly (PVC plastic bottle after cleaning, the use of the volumetric flask, pipette, glass containers should be cleaned in time.
7. Suggest using deionized water after using fluorine electrode in dry after cleaning to + 320 mv, it can prolong the service life of the electrode, and can not affect the next measurement.
