This research is based on the idea of the need for an innovative experimental learning media in the study of physical chemistry on electrolyte solutions conductivity concept. Through Research and Development method with the stages of analysis, design and development, a simple electrolyte conductivity measurement device has been produced. Based on the results of the research, the product was obtained in the form of an electrolyte solution conductivity measuring device that equipped with a user guidebook and an experimental worksheet of the electrolyte solution conductivity measurement. The electrolyte solution conductivity device is designed to measure the conductivity of an electrolyte solution. This measurement device is able to compare the conductivity value of fruit juices, vegetable juices and isotonic drinks quantitatively based on Kohlrausch’s law with simple and easy devices and materials. The validation result shows that the product is valid. The product was tested to chemistry education students using a feasibility test instrument. The result shows that the average of the value of the feasibility test is 93.85%. These results indicate that the constructed electrolyte conductivity meter is feasible to be used.
