Development of measuring devices total dissolved solid microcontroller-based with several variations of the conductivity sensor has been carried out. In the process of making this TDS product design the technique is first used brainstorming to determine the characteristics of the product to be made, then draw conclusions from the results of brainstorming that has been collected. Then the technique is done sampling by distributing open and closed questionnaires to determine the type of product. After the open and closed questionnaires are finished distributing, then conducted survey is market using a technique sampling, as well as determining the validity and reliability of the main products with products of competitors I, competitors II and competitors III. The steps problem to the sub problems are determined in order to classify the objectives that will be made in the design of the TDS product. Sub problem to sub solutions are carried out to determine the Quality Function Deployment (QFD) Product. The step sub-solution to the solution is determined to generate and evaluate alternatives by the sum of the paired matrices between attributes. Product design uses the nigel cross approach.
