We don’t stand still; we continuously adapt our portfolio to the demands of a changing world:
Portfolio expansion (2023): With the launch of our specialized Aqua division, we have purposefully expanded our range with innovative sensors and probes for the limnic sector (freshwater ecosystems). This means we now also offer high-precision solutions for water monitoring and water management.
