Tiivistelmä
Langis OY intends to design sensors for measuring water solutions for environmental usages, for example, natural water and wastewater from mining site. From water quality point of view, environmental sensors help measure properties of various contaminants in aqueous solutions, which is indispensable for environmental monitoring and industrial safety.
The prototype sensors used in this thesis include a conductivity sensor applied with two-electrode technology and a turbidity sensor using backscattering infrared light measuring method. The aim was to calibrate the two prototype sensors and evaluate the performance of both.
All the laboratory experiments were carried out in Metropolia Environmental laboratories (Leiritie 1, Vantaa). Samples of saltwater and milk were analysed. Performances and limitations of both sensors were found within the calibration curves, which provided satisfactory results of measurement.
