Voltameter "Hofi", complete

The production of hydrogen is currently a very important topic worldwide.
If there is a surplus of wind or solar energy, it can be used to produce hydrogen, which can then be converted into ‘green electricity’ using fuel cells.

With the ‘Hofi’ (Hofmann water decomposition apparatus), you can demonstrate how easily water can be split into hydrogen and oxygen.
The volume ratio of the gases produced can also be determined precisely by the graduation of the two legs. A centrally mounted scale allows the gas volumes to be read even from a greater distance.
This means that the device can be used for student experiments as well as for demonstrations. The two PTFE taps enable targeted and measured extraction of the gases.
The device comes with two silver electrodes. These are also available separately and are very easy to replace.
The device is complete and therefore ready for immediate use.
