This portable handheld meter makes determining the salt concentration of a solution fast and easy. Accurate measurements can be taken from a sample as small as 0.3mL. The Horiba LAQUAtwin salt meter features a flat sensor capable of making accurate measurements in seconds. Its selective electrode is unaffected by pH and the presence of other ions, enabling the accurate measurement of sodium ion concentrations and converting this to a measurement of salt concentration (NaCl%).
