酸度计使用时,易出现电极下部的玻璃泡的破损现象。不但毁坏了电极,且常影响试验。作者设计了一个玻璃电极保护罩,简单实用,效果很好。并不影响操作和试验效果。 保护罩为一圆筒形的塑料管(最好透明),见图,两端开口,下端切成锯齿形,以便溶液流通和电极洗涤。上部的圆筒纵向切去一半或2/3,上端固定有橡皮筋,将电极紧束于塑料上。使用时,从电极下端将保护罩套上,停于适当位置,扣紧橡皮筋即可。
Acidity meter used, prone to the lower part of the glass bulb breakage phenomenon. Not only destroyed the electrode, and often affect the test. The author designed a glass electrode protective cover, simple and practical, the effect is very good. Does not affect the operation and test results. The protective cover is a cylindrical plastic tube (preferably transparent), see figure, open at both ends, cut serrated at lower end for solution flow and electrode wash. The upper part of the cylinder is cut in half or two-thirds of the way longitudinally, with rubber bands attached to the upper ends, and the electrodes tightly tied to the plastic. Use, from the bottom of the protective cover will be placed on the electrode, stop in place, the rubber band can be fastened.
