Fouling the big problem for Fouling the big problem for sensors and systemssensors and systems
Anti-fouling technology is one of the most Anti-fouling technology is one of the most important support technologies for important support technologies for autonomous instrumentsautonomous instruments
Protection against or prevention of Protection against or prevention of possible fouling is of great importance for possible fouling is of great importance for a maintenance-free function over a longer a maintenance-free function over a longer period (long-term stability)period (long-term stability)
