RDO PRO-X opgeloste zuurstofsensor (In-Situ)

RDO PRO-X opgeloste zuurstofsensor

RDO PRO-X opgeloste zuurstofsensor

De Rugged Dissolved Oxygen (RDO-X) proces sensor maakt gebruik van optische technologie om zuurstof en temperatuur in water te meten. Deze sensor is ideaal voor procesmonitoring in veeleisende toepassingen zoals vuilwater (RWZI’s). De sensor reageert snel op temperatuur en zuurstofveranderingen en is ideaal om influent, effluent en verwerkingsprocessen te bewaken. De optische sensor heeft geen membraan, waardoor onderhoud en kalibraties tot een minimum worden beperkt.
