Myron L 442 Natural Water Standard Solution is used in calibrating a variety of 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 standard salts is necessary since natural water salt type and concentration can vary greatly by location.

442 Standard was developed by Myron L more than 40 years ago and remains the world's most accepted standard. All solutions are made under strictly controlled conditions and are NIST traceable.
