Key Features

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

  • Anti-Poisoning Design:Double-chamber reference​ with KNO₃ electrolyte​ and PTFE ring diaphragm​ provides high resistance to sulfide (S²⁻), cyanide (CN⁻), and heavy metal ions.

  • Robust Construction:PPS housing​ and PTFE diaphragm​ ensure long-term stability in abrasive and chemically aggressive media such as wastewater and chemical process streams.

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

Applications

  • Wastewater Treatment:​ pH monitoring in inlet, neutralization basins, and effluent discharge.

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

  • Chemical Process:​ Acid/alkali concentration monitoring in batch reactors and mixing tanks.

  • Mining & Minerals:​ Flotation processes and leach solution pH control.
