A. Conductivity/TDS Standard Solutions

Your Ultrameter II has been factory calibrated with the appropriate

Myron L Company NIST traceable KCl, NaCl, and our own 442™

standard solutions. Most Myron L conductivity standard solution bottles

show three values referenced at 25°C: Conductivity in microsiemens/

micromhos, the ppm/TDS equivalents (based on our 442 Natural

Water™) and NaCl standards. all standards are within ±1.0% of reference

solutions.

available in 2 oz., quarts/liters, and gallon/~3.8 liter bottles.

1. Potassium Chloride (KCl)

The concentrations of these reference solutions are calculated from

data in the International Critical Tables, Vol. 6. The 7000 µS is the

recommended standard.

Order KCL-7000

2. 442 Natural Water™

442 Natural Water Standard Solutions are based on the following salt

proportions: 40% sodium sulfate, 40% sodium bicarbonate, and 20%

sodium chloride, which represent the three predominant components

(anions) in freshwater. This salt ratio has conductivity characteristics

approximating fresh natural waters and was developed by the Myron L

Company over four decades ago. It is used around the world for

measuring both conductivity and TDS in drinking water, ground water,

lakes, streams, etc. 3000 ppm is the recommended standard.

Order 442-3000

3. Sodium Chloride (NaCl)

This is especially useful in sea water mix applications, as sodium chloride

is the major salt component. Most Myron L standard solution labels show

the ppm NaCl equivalent to the conductivity and to ppm 442 values. The

14.0 mS is the recommended standard.

Order NACL-14.0

B. pH Buffer Solutions (6Pfc)

pH buffers are available in pH values of 4, 7 and 10. Myron L Company

buffer solutions are traceable to NIST certified pH references and are

color-coded for instant identification. They are also mold inhibited and

accurate to within ±0.01 pH units @ 25°C. Order 4, 7 or 10 Buffer.

available in 2 oz., quarts/liters, and gallon/~3.8 liter bottles. Order SS.

C. pH Sensor Storage Solution (6Pfc)

Myron L pH Sensor Storage Solution prolongs the life of the pH sensor.

available in 2 oz., quarts/liters, and gallon/~3.8 liter bottles.

D. ORP Sensor Conditioner Solution (6Pfc)

Myron L ORP Conditioner Solution removes contaminants and conditions

the ORP electrode.

available in 2 oz. and quarts/liters. Order ORPCOND.
