The Apera PH60-SA (AI3727) is a professional handheld pH meter designed for strong alkaline solutions (pH 10–14) and high-salinity samples exceeding 5,000 ppm. It features the Swiss-made LabSen 845 electrode with a specialized high-alkali (HA) glass membrane that minimizes sodium-ion interference and alkaline measurement errors. Its Silver Ion Trap reference system and open-junction polymer electrolyte help maintain stable readings and reduce electrode clogging.
