Responsible for the traffic of commercial goods and for the protection of the people and the infrastructure, the customs officers have to control the weight of vehicles which want to cross the borders. Once the traffic legislation varies from country to country, even within political and economic unions like the EU or the Mercosur, the customs officers have the additional task to see if the vehicles at the borders comply with the national regulations. Certified for the legal control, light and very easy to handle, HAENNI scales are designed for those who need them daily to perform their duties, wherever the load is.
