Description
Technical field
The present invention relates to a kind of water quality detection is counted with PH.
Background technology
PH meter, is a kind of conventional instrument and equipment, is mainly used to the pH value of accurate measurement liquid medium, is mixed corresponding
Ion selective electrode can also measure ion electrode current potential MV values, pH meter be widely used in environmental protection, sewage disposal, scientific research,
The fields such as pharmacy, fermentation, chemical industry, cultivation, tap water.
The rank of acidometer and the accuracy of instrument are different two concepts, and instrument rank is with its accuracy not fully
Unanimously.The rank of acidometer is represented, example by the scale division value (resolution or minimum show value) of its indicator (referred to as based on electricity)
Such as：Index the instrument for 0.1pH and be referred to as 0.1 grade of instrument;Minimum show value is referred to as 0.001 grade of instrument for the instrument of 0.001pH, etc.
Deng.And the accuracy of instrument is electricity meter and the synthetic error of the supporting testing standard solution of electrode, it not only with electricity in respect of pass, and
It is more relevant with glass electrode and reference electrode.From actual operation requirements, the scale division value of electricity meter is 0.1～0.001pH, if
If necessary, according to current scientific and technological level, more accurate electricity meter can be produced completely.But, due to structure and manufacture etc.
The reason for aspect, the performance of common electrode can't reach completely preferable degree.The repeatability error and reference of glass electrode
The solution junction potential stability of electrode is all not better than 0.01pH.Therefore, the resolution of electricity meter is high again, and instrument test accuracy is all
Hardly possible is better than 0.01pH.But, select high-resolution instrument to overcome to greatest extent or eliminate electricity meter to test error
Affect.
At present existing water quality detection counted with ph in-convenience in use, structure is not compact, and certainty of measurement is not high.
