Alyza is here to Maximize your data

The Alyza IQ PO4 orthophosphate analyzer is another component for the IQ SENSOR NET. It can be easily integrated into new and existing systems just as simple as a sensor

Maximize your data, Minimize your maintenance and reagent consumption: the new Alyza IQ

The Wet Chemistry revolution is now.

With WTW designed disruptive technology at the heart of the new Alyza IQ range, extremely accurate and reliable measurement results have been realized with extremely low reagent use, maintainance and downtime.


  • 24/7 reliable and accurate measurement
  • low operational costs
  • extremely low maintenance
  • ease of use

Fields of application

Ammonium measurement with Alyza IQ NH4

Indophenol method according to DIN 38 406

Wastewater treatment plant effluent monitoring:
  • High measuring accuracies even at low concentrations
  • Easy handling due to optimized user interface
  • Increased employee protection by safe exchange of reagents
River monitoring:
  • Long lifetime of reagents due to minimum consumption
  • Minimal maintenance effort reduces work and travel times
  • Full remote access via IQ Web Connect, at any time

Orthophosphate measurement with Alyza IQ PO4

Molybdate-Vanadate method (Yellow method)

Precipitation control:
  • Automatic cleaning reduces maintenance effort and increases operational safety
  • Reduction of precipitant costs without overdosing by reliable and fast measurement
  • One instrument for up to two sample streams
Wastewater treatment plant effluent monitoring:
  • Precise results via automatic 1- and 2-point calibration
  • Easier everyday life due to self diagnostics with display of reagent lifetime
  • Requirements for further decreasing effluent values are not a problem due to low measuring range
