Mobofoto: a mobile platform for concentration measurement through colorimetric analysis
Traditional colorimetric measurement is widely used in chemical concentration estimation. However, compared to the laboratory solutions for accurate measurements with professional measuring equipment, colorimetric measurement is often more qualitative than quantitative. It would be most productive …
