RINKO-Profiler

Multi-parameter CTD
with fast optical DO sensor

The RINKO-Proﬁler is a CTD with a fast-responding DO sensor as standard conﬁguration. Fast responsivity reduces observation
time, while achieving a detailed DO vertical distribution. The 1 GB internal memory allows for recording up to 1000 proﬁles (of100 m depth at 0.1 m of sampling rate) and the internal rechargeable lithium battery allows continuous use up to 10 h.

RINKO-Profiler variations

The YODA proﬁler (“Yoing” Ocean Data Acquisition Proﬁler) is a “tow-yo” instrument toproﬁle the water column with high spatial resolution from small boats without occupying
much space. The brush at the top of the instrument allows for a stabilizing eﬀect on thefree-fall sinking speed, which is approximately constant at 0.2 m s⁻¹.
