Different samples should choose the corresponding ph probes

Routine samples:common clear water samples, have a certain H + or OH- ion concentration, good fluidity. For example, dilute hydrochloric acid, sulfuric acid solution.

Samples containing solid impurities:Water samples containing suspended solids, good fluidity, and suspended solids without adhesion. Such as printing and dyeing water, fruit juice, sampling of light pollution water

Mixture sample:nosuspended thhings after long time storage, good liquidity. For example, milk, blood, beverages, alcohol and so on.

Highly polluting samples:The components of the sample have strong adhesion, little moisture, easy to adhere to the glass bulb or reference salt bridge surface. Such as paint, cooking oil, cosmetics and so on.

Low conductivity samples:Water samples have lower conductivity and lower H + or OH- ion concentrations. Such as river water, tap water, rain, pure water, deionized water, distilled water and so on.

E-201-Z:large sampling volume≥10mL. For semi-solid sample measurement, can pierce the sample for internal pH measurement, such as pork, soil and so on

E-201-P:small sampling volume≥0.2mL, for the pH measurement of the sample surface, such as skin,paperand so on
