一定の測定条件
再現性のある正確なpH測定には一定の測定条件が必要とされる。
温度：もし別々のサンプルのpHを比較する場合は、同じ温度で測定した上で比較しなければならない。
均一性：沈殿物がたまる溶液は、物理的にも科学的にも均一になるように撹拌しなければならない。時間も重要な役割を果たす。特に緩衝能力が低いとき、つまり塩分の低い、あるいは全く塩分のないものの場合、特にそうである。たとえばCO2（大気からの）は、このような塩分の低い溶液中にとけこんでpHの変化を引き起こす。

Certain measurement condition
Accurate and reproducible measurement of pH requires certain measurement condition.
Temperature: If comparing pH of verious samples must be done in the same templature.
Homogeneity: Solution where standing sediment must be stirred homogeneously in a phiscal and scientific manner. Time also play an important roll. Especially, this applies to low level of buffering capacity, in other words, low level of salt or no salts. For example, CO2 (from atmosphere) will be melt solution such low level of salt and trigger a change in pH.

Condition of measuring
A condition of measuring is required for measuring correct pH that is likely to be reproduced.
Temperature, if pH of different sample is compared, it must be compared upon measuring at the same temperature.
Evenness: The solution where sediment remains must be stirred to make it even physically and scientifically.
Time plays an important role. It is particularly true when buffering ability is low; that is when amount of salt is small or no salt is included.
For example, CO2 (from atmosphere) causes change of pH by dissolving into solution where small amount of salt is included.

Measurement conditions of certain
Measurement certain conditions are required for accurate pH measurements reproducible.
Temperature: When comparing the pH of the separate samples, then the comparison must be on was measured at the same temperature.
Uniformity: The solution of the precipitate accumulate and must be stirred to be uniform even in science and physically. I play an important role in time. When buffering capacity is particularly low, or no salt at all, or low salinity but if this is the case in particular. For example CO2 (from the atmosphere) causes a change in pH to blend into the solution of low salinity such.

Fixed measurement criteria
Reproducible precise pH measurements require fixed measurement criteria.
Temperature: to compare pH values of various samples, measurements must be conducted at the same temperature.
Uniformity: physically and scientifically, solutions filled with precipitants have to be agitated to reach uniformity. Time also plays a crucial role. Particularly at a lower buffering capacity of low salinity or totally deprived of saline. For instance, CO2 (from atmosphere) will induce pH variation when dissolved in such a solution with low salinity.
