Specific Conductance, pH, and Turbidity Meters
meterWith 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.
