Measuring principle

pH measurement

The pH value is measured based on the electrochemical potential generated by H⁺ ion accumulation on the membrane glass, with an integrated Ag/AgCl reference system. The measured voltage is converted to a pH value using the Nernst equation.

Measuring system

• Transmitter: CML18
• Smartphone with Smartblue app (optional)
• Sensor: Memosens CPL53E
