本装置由一盐传桥导H~+电位而测定pH。验证结果表明,性能稳定可靠(变异系数=0.14％或0.28％,标准差=±0.0107或±0.0207),并与常法极其相关(P>0.2,γ=0.999)。适用国产普通型酸度计测试小容量样品。
The device by a salt bridge conduction H ~ + potential and determine the pH. The validation results showed that the performance was stable and reliable (coefficient of variation = 0.14% or 0.28%, standard deviation = ± 0.0107 or ± 0.0207) and was significantly related to the normal method (P> 0.2, γ = 0.999). For domestic common type acidometer test small volume sample.
