This research study focuses on the design and construction of an electronic tester using locally soured materials for measuring the concentration of table salt in solution. Salt, also known as table salt is a mineral that is composed primarily of sodium chloride (NaCl), this is a chemical compound belonging to the large class of ionic salts. The operating system consists of sensor, which senses the concentration of salt in solution, the signal amplification unit, which amplifiers the signal from the sensing unit and the display unit, which displays the concentration of salt in various solutions. The realization of the research study was achieved using different components like resistors, capacitors, op-amp, CA3162E, CA3161E and seven segment display. The design parameter was obtained from component calculations configured with the amplification unit to work with the sensing and display unit. These components were connected together on a veroboard with the aid of different tools. After completion of work, the project was tested and the percentage error values obtained by dipping the sensor in salt concentration were 0.58, 1.43, 1.73, 2.10, 2.21 respectively, which was relatively low compared to other electronic salt tester.
