GAOTek Aquaculture Digital Ion Selective Electrodes Nitrate Meter Water Hardness Tester
GAOTek Aquaculture digital ion selective electrodes nitrate meter water hardness tester is a kind of electrochemical sensor.
Description
Overview
GAOTek Aquaculture digital ion selective electrodes nitrate meter water hardness tester is a kind of electrochemical sensor that uses membrane potential to measure the activity or concentration of ions in the solution. When it comes into contact with the solution containing the ions which are to be measured, it will generate contact with the sensor at the interface between its sensitive membrane and the solution. Ion activity is directly related to membrane potential. Selective ion electrodes are also called membrane electrodes. This type of electrode has a special electrode membrane that selectively responds to specific ions. The relationship between the potential of the electrode membrane and the ion content to be measured conforms to the Nernst formula.Â
