Specific Conductance, pH, and Turbidity Meters
With
each use of the specific conductance, pH, or turbidity meter, calibrate the
instrument according to the manufacturer’s instructions (kept with the meter).
Use a calibrated solution that is within the range of the water sample to be
measured. Label specific conductance and pH buffer solutions with the date
opened and discard working solution weekly. Each piece of equipment has a daily
logbook; record all calibrations in the appropriate logbook. |
