PH Sensor - Used in any laboratory demonstration, like a traditional hydrogen meter. Provides automatic data collection, graphing and data analysis. Work with the sensor allows the study of acids, alkalis and bases, acid-base titration, monitoring the change in the level of hydrogen during chemical reactions, during photosynthesis, studying acid rain and buffer solutions, studying the composition of water in rivers and lakes. Range: pH 0-14. Included: a set of capsules for preparing a buffer solution, a solution for storing electrodes - 2 sets, bottles for a solution - 6 pieces, an electrode holder
