Ammonia Analyzer Package

Reagentless Monitoring of Dissolved NH3

Continuous on-line measurement of ammonia using pH appropriate sensor technology. Uses specific sensor adapted to operational pH range to ensure correct measurement. Determine free ammonia, total ammonia, and NH3-N for control and reporting purposes. Complete system mounted on wall mountable back panel to facilitate installation. Sample header includes ammonia sensor, pH sensor and temperature sensor.

 

FEATURES AND BENEFITS

 

  • No regents needed for continuous on-line monitoring
  • Measures ammonia concentration and logs values
