All
calibration solutions have a certificate of analysis available. Solutions
are made of reagent-grade KCl and pure 5 MW water. Use solutions with
442 concentration values (40% Na2SO4,40% NaHCO3, 20% NaCl) for most applications.
Seawater or brackish water applications require solutions with NaCl concentration
values. All values listed in tables are referenced to 25°C.
Single-use pouches are sealed to ensure freshnesstake these convenient
buffer solutions anywhere! A µS-to-ppm conversion table is printed
on each pack for quick reference. Sold by the each package.
