potassium ion sensor for hydroponics

... into contact with a solution containing the target ions, a membrane potential directly related to the ion activity is generated at the interface between its sensing membrane and the solution. The ion-selective electrode functions as a half-cell (except...

... ion concentration in the water is high, potassium ion compensation is required. The ammonia nitrogen sensor is composed of ammonium ion selective electrode, potassium ion (optional), pH electrode, and temperature electrode to form an integrated sensor....

..., pH electrode and reference electrode (potassium ion is optional) as standard. In the process of measuring ammonia nitrogen in water, automatic pH and temperature compensation are performed to make the measured value more accurate. The sensor can be...
