-4H-JENA Engineering Showcases Comprehensive Underwater Sensor Portfolio at Ocean Business 2025

Jena, Germany: -4H-JENA Engineering, a leader in high-precision seawater sensor and measuring systems, is set to showcase its extensive range of CONTROS brand sensors and FerryBox systems at Ocean Business 2025. With a strong emphasis on environmental monitoring, the company will highlight how its technology supports marine research, climate change studies, and commercial oceanographic applications.

Among the innovations in focus will be the CONTROS CombiSensor CO2 / CH4, which integrates carbon dioxide and methane gas measurements into a single compact unit. Designed for deployment on autonomous platforms with limited payload capacity, the sensor is also ideal for installations on commercial vessels and fixed monitoring stations, enabling long-term, reliable data collection for climate research and environmental assessment.

In addition to the latest sensor developments, 4H-JENA Engineering will spotlight its FerryBox technology, a proven solution for continuous seawater analysis. Widely adopted by research institutions and environmental agencies, FerryBox provides real-time insights into key parameters such as pH, oxygen, salinity, and CO2 levels, supporting efforts to track ocean acidification, pollution, and climate-driven changes in marine ecosystems.

“We are delighted to return to Ocean Business, one of the key events for the marine technology community,” said Uwe Posner, Senior Sales Manager at -4H-JENA Engineering. “Our CONTROS sensors and FerryBox solutions are designed to meet the evolving needs of researchers and industry professionals seeking high-quality ocean data. We look forward to discussing our technology with attendees and exploring new opportunities for collaboration.”
