This sensor adopts ion-selective electrode technology, The electrode is highly selective to potassium ions, and its working principle is based on the selective ion exchange and diffusion between the electrode membrane and potassium ions in the solution to be measured, thus generating a potential difference. By measuring this potential difference, the concentration of potassium ions in the solution can be calculated according to the Nernst equation. plug and play. No calibration is required for the first use.

Application fields: agricultural monitoring, environmental monitoring, chemical production, and natural water testing.
