Tyflo lab

A small vibrating indicator is designed to prevent liquid from overflowing over the rim of the vessel. With its help, a blind or visually impaired person can easily make their own favorite drink - tea, coffee, pour water, milk, juice and other liquids. The indicator is easy to use and has three contacts that vibrate when they come into contact with the liquid. To start using, place the indicator on the edge of the vessel so that the contacts are inside. Start pouring liquid. When the liquid reaches two contacts, the indicator will begin to vibrate. If you continue to pour liquid, and it reaches the third contact, the vibrating signal at the indicator will increase. Size: 6x4x2.5 cm.
