The NH6000sc analyzer represents the evolution of ammonium analysis from Hach®. It is the new and improved replacement for the Amtax sc analyzer. It has increased performance and reliability and uses fast, accurate and reliable GSE (gas selective electrode) technology. It provides reliable measurements with automatic calibration, validation and cleaning. It is designed for a wide range of aquatic applications. It helps maintain a smooth and consistent nitrification process by continuously and accurately monitoring ammonium ions, which can be difficult under ever-changing conditions. Compared to competitive analyzers, it features a low detection limit (0.02 mg/L NH4-N), a 5-minute measurement interval and low maintenance requirements (reagent replacement only every 6 months).
