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.
