We participated in the Teaching Aids Fair that was held at the Belgrade Fair from 28.10. - 01.11.2015. In addition to the most advanced products for studying of renewable energy from the company Horizon Educational and a large number of sensors and measurement devices science classes from the company Vernier, we had the opportunity to introduce our new device LabKIT. LabKIT is the teaching aid for biology, chemistry and thermodynamics experiments. Children and other visitors at the fair had a chance to measure the strength of the grip by using LabKIT, a dynamometer and application developed by students of School of Electrical Engineering who were practicing in our company.
