The Hach’s Amtax sc digital on-site analyzer with a gas selective electrode is engineered for the high precision determination of ammonium concentration directly at the tank. This analyser offers a high degree of accuracy due to selective GSE instrumentation and needs only minimal supervision due to automatic cleaning, calibration and self diagnosis. Amtax sc analyzers are ideal for installation directly on the tank edge, for fast reaction times in the closed loop control. In addition, they are available with a weather proof housing for outdoor setup or optional with a transparent door for indoor setup. Easy access to reagents and wear parts.
