  • Ammonium ions are measured using the ion-selective method, which consists of a working electrode, a reference electrode, an ion-selective membrane, and an electrolyte. Only the ammonium ions to be measured can pass through the ion-selective membrane and undergo a charge change, generating a potential at the working electrode that is proportional to the ion concentration and a constant potential at the reference electrode.
  • Fast response with a minimum measurement cycle of only 1 second
  • Applied to surface water monitoring, domestic wastewater, agricultural wastewater, and municipal wastewater.
  • Connected to the TRM transmitter and Ulik-Server Cloud Service to realize remote real-time monitoring of data and remote control.
