OP-213型酸碱浓度计是匈牙利 RADEL-KIS 电化学仪器公司生产的一种小型仪器。它可不经滴定,只测 pH 就得到酸或碱的浓度。它采用的方法有突出优点,值得借鉴。1.结构特点OP-213分为七个主要部分(见图1)。其中电极系统有独到之处。它由甘汞参考电极、
OP-213 acid-base concentration meter is Hungary RADEL-KIS electrochemical instrument company produces a small instrument. It can be titrated to determine the acid or base concentration without titration. It uses the method has outstanding advantages, it is worth learning. 1. Structural Features The OP-213 is divided into seven main sections (see Figure 1). The electrode system has its own uniqueness. It consists of calomel reference electrode,
