conductivity standard

These standard solutions and buffers from Myron are made under controlled conditions using reagent-grade salts. These salts are combined with deionized water having a resistivity of at least 5 megohms-cm of purity. They geenrate an accuracy of?1% according to the standards of International Critical Tables and traceable to the National Institute of Standards and Technology. These solutions are used for factory calibration in order to ensure the proper instrument accuracy. The frequency of conductivity re-calibration relies on the use. pH models require a pH 7 Buffer every 1-2 weeks, and checked with pH 4 and/or 10 Buffers at similar intervals. The pH Sensor Storage Solution is advisable for keeping the pH sensor moisturized.
