Clean Sensors, Clean Data

ProbeGuard controls biofouling on various moored sensors by enclosing them in a chamber that is opened and flushed to collect data. A dilute chlorine solution is periodically added to the chamber to bathe all sensors in the anti-foulant. Results from multiple environments have been impressive.
