Fast optical DO sensor for integration

RINKO FT

■ Description
The RINKO series is based on the op cal (phosphorescence) principle which is now widely known as a remarkably fastresponse oxygen sensor with a high accuracy. As a new member of the RINKO family, the RINKO FT (model name: ARO-FT,AROD-FT) had overcome a well-known tradeoﬀ between fast responsivity and stability of oxygen sensing foils. The RINKOFT not only retains the fast response Ɵme iden cal to that of conven onal RINKO series but also has greater accuracy andstability by incorpora ng high-quality mulƟpoint calibraƟon and improved sensing method. The RINKO FT is primarily
designed to target Argo float opera ons. However, its compact, lightweight, and commonly used communica on protocol
widen the choice of pla orms for installa on. The RINKO FT enables DO measurements with a high spa al resolu on,which will contribute to the understanding of new aspects of physical/biochemical processes.
