Myron L pH and ORP Sensor Storage Solution, SS-Quart, Quart Size (32 Oz)

All Myron L handheld instruments are factory calibrated with NIST traceable Standard Solutions having specific conductivity/ppm values. Myron L Company Standard Solutions are made under strictly controlled conditions using reagent grade salts. These salts are mixed with deionized water having a resistivity of at least 5 megohms-cm purity.

Myron L Company Standard Solutions have an accuracy of +/-1% based on values published in the International Critical Tables and traceable to the National Institute of Standards and Technologies.

The conductivity Standard Solutions and pH buffers listed below are used for factory calibration. Regular use of these solutions is recommended to ensure specified instrument accuracy. Frequency of conductivity recalibration depends upon use, but once every month should be sufficient for an instrument used daily. 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.
