Important Considerations For pH Meter Maintenance
There are some important considerations which should be borne in mind when purchasing a pH Meter:-
All pH Meters must be calibrated. This means checking against a known standard for accuracy
The electrode should always be immersed in solution. Consider the cost of replacement electrodes when purchasing a pH Meter
Readings are affected by temperature. The pH Meter should be calibrated at the same temperature as the solution being tested
Many laboratory pH Meters also incorporate a Conductivity Meter meaning that it is possible to test a substance for pH level and conductivity using the same piece of electronic equipment. Such machines are frequently manufactured with the incorporation of automatic temperature compensation meaning that no adjustment is required for temperature.
