The Apera PH60-PW (AI3723) is a professional handheld pH meter designed specifically for measuring pure and low-ionic-strength water, including reverse-osmosis (RO), distilled, deionized (DI), boiler, drinking, surface, storm, and well water. It combines the Apera PH60 handheld meter with the Swiss-made LabSen 805 pH/temperature combination electrode, engineered to address the unstable, drifting readings that conventional pH electrodes often produce in low-ionic-strength samples. The electrode features triple ceramic junctions for rapid electrolyte discharge and an L-type, olive-shaped glass membrane with resistance below 50 MΩ and a large hydrogen-ion sensing area. Together, these features help stabilize measurements in water containing very few dissolved ions. The meter also supports measurements in mixed nutrient solutions, making it useful for checking source water before nutrient mixing and verifying pH afterward. Its IP67-rated housing, three-color backlit display, automatic temperature compensation, and rugged carrying case make it suitable for daily use in commercial cultivation facilities.

Key Advantage: The Apera PH60-PW is specifically engineered for pH measurements in RO, DI, and other low-ionic-strength water sources where conventional probes may produce unstable or drifting readings. Its triple-junction LabSen 805 electrode helps stabilize measurements, while automatic calibration, reading lock, and configurable pH alerts simplify routine testing. The replaceable electrode also allows the meter body to remain in service when the probe eventually needs replacement, making it practical for commercial facilities that routinely test source water before preparing nutrient solutions.
