The Ull Meter is the first instrument in the world that gives an objective and reproducible measurement of individual stress reactions on humans. As a blood pressure monitor shows the blood pressure, the Ull Meter presents an objective numeric for the body and mind's state of stress.
After the development, Ull Care A/S asked DIS to help test whether or not the instrument was designed for rugged duty. DIS contributed with a test design that showed how precise the instrument measures after constant use. The design also tested the robustness of the instrument. Both tests came out positive and a supplementary “break test” showed a durability of 20 years.
