Aanderaa products have played important roles within the oceanographic community since 1966. The Aanderaa Current Meters were from the beginning known for their reliability and were early considered as "the standard" when it came to current measurements. Over the years the oceanographic product portfolios have undergone an evolution and the range of products have been broadened substantially. Today the oceanographic products are utilizing the newest technology comprising, among others, the most powerful microcontrollers and digital signal processors. Advanced software solutions and powerful processors are utilized in the data loggers, and XML– and modern Bus technology give safe and fast data transfer. Sensors are utilizing the most advanced multi-frequency acoustic technology as well as optical technology.
