 WTW IQ SensorNet Alyza Analyzer NH4

The IQ Analyzer features a revolutionary MultiValve that dramatically reduces reagent use and maintenance requirements.

  • Features
  • Specifications

The Alyza IQ NH4 is an online, cabinet-style analyzer used for continuous monitoring of ammonium in a municipal water resource recovery facility. This analyzer is weatherproof and can be deployed anywhere in the wastewater treatment process. Applications include monitoring biological tanks to help control ammonium-based aeration control and plant effluent locations to ensure compliance. An innovative MultiValve within the analyzer significantly reduces reagent use to 15 µL per measurement decreasing the analyzer’s regular maintenance requirements. The analyzer is available as a single-channel or two-channel instrument allowing you to sample from two different locations. The IQ Analyzer can be used as a stand-alone analyzer or be incorporated into an IQ SensorNet network of sensors. The IQ Analyzer provides accurate measurements with minimal maintenance requirements.

IQ Analyzer NH4 offers:

  • Reliable, accurate measurements at low measurement concentrations
  • Extremely low reagent consumption, 15 µL per measurement
  • Automatic calibration, 1 or 2 point
  • Automatic cleaning, lowering maintenance requirements
  • Serviceable – safe and easy replacement of reagents, no need for expensive service contracts
  • One or two channel versions available
  • Reliable sample delivery pump built into the cabinet
  • Uses Indophenol method of detection
  • Filtration unit allows analyzer to process samples with solids concentrations up to 6,000 mg/L

Applications include:

  • Ammonia-based aeration monitoring and control
  • Effluent monitoring to ensure compliance
