RINKO W

■Description
Rinko W is an autonomously deployable data logger for long-term DO measurements. In order to protect the sensing foil against accumulating bio-fouling, the instrument has a mechanical wiper to sweep the optical window. The optical sensor does not have a membrane neither electrolytes, thus, it need less maintenance than electrode or galvanic sensors.
