Low-cost Laboratory Stand for Turbidity Measurements
Fresh water becomes scarcity not only worldwide but also in some developed countries. Therefore there is more and more attention paid to quality of this exceptional natural resource. Clarity or its inverse known as turbidity is key feature of water characteristic. Smaller, easier to use and more convenient device to measure this parameter could be constructed with significantly lowered costs thanks to improvements in electronic components. Research presented in this paper is aimed at constructing a laboratory stand with which a progress could be made in development of such device. Construction of optical system with limited set of items is discussed as well as design and assembly of opto-electronic transducer.
