Voltameter “Hofi”, complete

The “Hofi” (Hofmann water-decomposition apparatus) lets students demonstrate how readily water can be split into hydrogen and oxygen — a timely link to green-hydrogen energy. Its two graduated arms with PTFE taps hold 30 ml each (0.5 ml graduations), so the volume ratio of the gases can be measured precisely, while a central scale keeps the readings legible from a distance. Supplied complete and ready to use, it comes with two replaceable silver electrodes, 4-mm connection sockets in the base plate and operating instructions. Overall dimensions 160 x 120 x 460 mm (L x W x H), mass approx. 353 g; suitable for both demonstrations and student experiments.
