Myron L KCl-70 Conductivity/TDS Standard Solution, Quart Bottle (32 Oz)

- KCl-70 Conductivity/TDS standard solution

- (1) Quart Bottle 

Myron L conductivity instruments and monitor/controllers are calibrated to read in ppm/442, ppm/NaCl, or microsiemens. All three values are listed on the Standard Solutions. The relationship among these standards can be seen in the table and graphs that follow.

442 Natural Water™ Standard Solution is used in calibrating many Myron L Instruments. It is the best choice when measuring boiler and cooling water samples, city water supply, lakes, wells, etc. "442" refers to the combination of salts mixed with deionized water to comprise this standard: 40% sodium sulfate, 40% sodium bicarbonate, 20% sodium chloride. A combination of salts is necessary since natural water salt type and concentration can vary greatly by location.

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, 1000 ppm of NaCl has a conductivity of 2000 micro mhos. Note how this is 1:2 relationship is continuously variable throughout the curve and decreases as NaCl increases.

KCl Standard Solution is used to calibrate conductivity instruments that read directly in microsiemens (micromhos) or millisiemens (1000 microsiemens). KCl (potassium chloride) is a very stable salt and is an international calibration standard for conductivity measurement.
