AL-AC130 Ammonia Nitrogen Automatic Monitoring Instrument

This method is suitable for wastewater with ammonia nitrogen in the range of (0-500) mg/L. Excessive calcium and magnesium ions, residual chlorine, or turbidity may interfere with the measurement.

A pollution source installed in a specific location, applied in the field of water quality monitoring, mainly used by sewage treatment plants.
