Individual, high performance RAS for every research need

The MicroRAS is our answer to researchers’ needs for flexibility. Individual RAS systems are the perfect tool for digestibility trials, comparison of different environmental parameters and investigation on the variability between culture units, equipment comparisons and many other experiments.

Furthermore, MicroRAS features a wide array of sensors, automatic data logging and configurable software. This makes these systems highly autonomous, yet customizable. The system is designed to maintain the strictest water quality requirements for salmonids under the toughest conditions, in a compact footprint.
