Hanna Ammonia Combination Ion-Selective Electrode (ISE) - HI4101

The HI4101 Ammonia Combination Ion-Selective Electrode provides reliable measurement of ammonium and ammonia concentrations in a wide range of sample types. Its gas sensing design incorporates a PTFE membrane, allowing ammonia gas to diffuse into the inner electrolyte layer for precise detection. The robust Delrin® body ensures mechanical durability and chemical resistance.

• Wide detection range of 0.02 to 17,000 mg/L for NH₃, and 0.016 to 14,000 mg/L for NH₃-N, suitable for diverse laboratory and industrial requirements.
• Replaceable PTFE membranes extend the operational lifecycle of the electrode.
• Body length of 120 mm with a 12 mm outer diameter fits most laboratory setups.
• Includes a 1-meter coaxial cable with a BNC connector for universal compatibility with common ion meters or pH meters supporting ISE sensors.
• Optimal operation is maintained at pH levels greater than 11 and within a temperature range of 0 to 40 °C.
• Delivers approximate slope of -56 mV per concentration decade for accurate calibration and repeatable analytics.
• Constructed for continuous use in environmental monitoring, agricultural water analysis, wastewater quality control, and winery applications.

This electrode is a professional laboratory sensor designed for use in water quality laboratories, industrial wastewater treatment plants, agricultural testing facilities, and academic research. Package includes the combination ion-selective electrode, 1 m cable, and technical data sheets.
