2, Maintenance and precautions
1) When the electrode is not in use or long home for the first time, the ball electrode
immersion has 3.3 mol / L KCl activated 2 hours.
2) When measuring, you should be washed in distilled water and wipe dry with paper
to prevent impurities into the electrode bulb and the liquid junction should also
immersed in the test fluid.
3) PH composite electrode E-201, do not need to add supplementary
reference solution.
4) PH electrode has a long soak in distilled water should be avoided or protein
solution and washed with acid chloride solution and to prevent contact with silicone
grease.
5) with standard solution preparation:
PH4.01, PH9.18 two standard solutions were bagged dose preparation.
Formulated 3.3 mol / L potassium chloride solution: in the hand on the drug analytical
balance 246 g of potassium chloride were weighed, dissolved in 1000 ml of deionized
water Serve.
