Hydrazine analyzer 7150 model

In thermal power generation plants, hydrazine is injected to remove oxygen dissolved in the boiler feedwater; hydrazine is an important measurement item in terms of water quality control. This system performs continuous measurement of hydrazine stably by the "polarographic three-electrode method."


  • Adopts the polarographic three-electrode method.
  • Capable of performing continuous measurement from low to high concentration with accuracy.
  • Equipped with a self-diagnostic function to improve reliability.
  • Provided with an automatic calibration function to perform calibration when the unit is stopped.
  • More compact than the conventional 714X model with a reagent tank installed in the panel.
