The NH3-selective gas electrode (high conc.) is designed for measuring high ammonium concentrations in samples such as wastewater. It uses replaceable membranes optimized for faster response times after high-concentration measurements and improved signal stability under high ammonium levels. The electrode is part of a system that converts ammonium ions to ammonia using NaOH, with ammonia diffusing through a gas-permeable membrane to a combined pH sensor. Replacement membranes are available in kits of 20 for cost-effective maintenance in contaminated environments. The part is compatible with the Metrohm plug-in head G and requires the 6.2104.020 electrode cable for operation.
