Key Features

  • Memosens 2.0 Digital:​ Inductive coupling eliminates moisture issues and stores calibration data in the sensor head for predictive maintenance.

  • Anti-Poisoning Design:​ Double-chamber reference​ with KNO₃ electrolyte​ provides high resistance to sulfide (S²⁻) and cyanide (CN⁻) poisoning.

  • Robust Construction:​ PPS housing​ and PTFE diaphragm​ ensure long-term stability in abrasive and chemically aggressive media.

  • Plug & Play:​ Pre-calibration capability allows lab calibration and quick sensor replacement without on-site recalibration.

Applications

  • Wastewater Treatment:​ pH monitoring in inlet, neutralization, and outlet stages.

  • Industrial Water:​ Cooling water, boiler feedwater, and chemical process control.

  • Mining & Minerals:​ Flotation processes and leaching applications with abrasive slurries.
