pH Buffers listed below are used for factory calibration. Regular use of these solutions is recommended to ensure specified instrument accuracy. pH models, depending upon use, should be recalibrated with pH 7 Buffer every 1-2 weeks, and checked with pH 4 and/or 10 Buffers at similar intervals. pH Sensor Storage Solution is recommended for keeping the pH sensor wet. Replacement sensors are also available.
