Doroodmand, Mohammad Mahdi; Maleki, Norooz; Kazemi, Hojjatollah – Journal of Chemical Education, 2010
A simple, sensitive, and portable viscometer has been designed using an opto-mechanical mouse. The viscosity of a fluid is measured using the infrared light-emitting diodes and the optical diodes of an opto-mechanical mouse. These components are positioned near the top and bottom of a glass tube containing the fluid to be measured. The viscosity…
