Ammonia Analyzer uses coulometric titration technology.
Laboratory and Research Supplies and Equipment

Ammonia Analyzer uses coulometric titration technology.

Using one type of environmental-friendly reagent (dedicated electrolyte), AT-2000 can measure ammonium-nitrogen (NH4-N) from 0.00–2.00 mg/L, 0.00–20.00 mg/L, and 0.00–200.0 mg/L with respective sample volumes of 10.0, 1.0, and 0.1 mL and less than CV 3% precision. Measurement range is not interfered with by turbidity or color of sample, and operation does not require end-user to have any...
