According to European and German law, it is prohibited to dispose of old electronic
devices into household waste, but must be collected and disposed of separately.
Amplifiers and measurement units manufactured and sold by Althen Mess- & Sensortechnik GmbH
serve B2B purposes only. Therefore, those old appliances must not be given to the communal disposer,
but must be given back to the seller or disposed of properly. If you need any further information, please
contact your local authorities.
These measures serve to protect the environment and allow recycling and recovery of valuable
materials. Furthermore, do electronic devices contain substances that may cause damage to the
environment if burned or dumped with normal household waste.
