1. Conductivity Electrode User Manual 1 Application This conductivity electrode is the measuring element of the conductivity meter It used to measure the conductivity value of the aqueous solution or as a conductance titration 2 Model and Main Technical Parameters Model DJS O 1 260 DJS 1 DJS 10 Vessel 0 1 0 02 0 640 2 1 0 2 10 2 Constant 3 Use and Maintenance l There are two kinds of conductivity electrode shiny electrode and platinum black electrode platinum plated black aims to increase the effective area of the electrode sheet and relieve being polarized So in the measurement of large conductivity solutions using a platinum black electrode is more appropriate For the platinum black electrode before use it can be immersed in deionized water to prevent the platinum black inerting When platinum black coating off or fade then you must re plating platinum black to ensure the accuracy of the measurement readings The cell constant marked on the electrode is just for reference If you want to test the cell constant is accurate or not you can lookup the corresponding conductivity value K according to the concentration and temperature of the tested solution Then the cell constant Q is calculated based on the measured resistance R The formulais Q K X R See table below for details Model Solution Solution Conductivity Value Concentration Temperature C DJS 0 1 0 001mo1l L KC2.
