NaCl Standard Solution - Quart
The Myron L NaCl Standard Solution is offered to calibrate instruments that measure any sample that is predominately NaCl (sodium chloride), such as sea water, brackish water, etc. As can be seen in the graph at right, 1000 ppm of NaCl has a conductivity of 2000 micromhos. Note how this 1:2 relationship is continuously variable throughout the curve and decreases as ppm NaCl increases.
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 Technology.
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. Myron L® solutions are available in quart/1 ltr., gallon/3,8 ltr. and 2 oz./59 ml plastic bottles, ready to use. (Custom value standards only offered in gallon/3,8 ltr. size bottles.)
