| 摘 要： | 由于一些自动校准型pH计设置的校准点与计量检定规程要求的pH 7(或电计等电位值)无法对应,探讨了用pH 6.86点代替pH 7点,解决了电计输入阻抗引起的示值误差无法按照计量检定规程要求进行检定的问题。通过实验验证了该方法的可行性。

| Abstract: | Based on the fact that some calibration points setting in some automatic calibrating pH meters do not correspond to the equipotential value requirements of the verification regulation, how to use point pH 6.86 instead of pH 7 was discussed. In this way, the problem that input impedance of pH meter can not measured in accordance with the verification regulation was solved. The feasibility of this method was proved by experimentation. |
