Observatory reference: DELOS A[2009-***], DELOS B[2009-****]

Standard: DELOS A, DELOS B

The C-Star incorporates a novel monolithic housing with a highly integrated opto-electronic design to provide a low cost, compact solution for underwater measurements of beam transmittance. The instrument is capable of either free space measurements, or through the use of an optical flow tube, flow-through sampling with a pump. It can be used in profiling, moored, or underway applications. C-Star’s analog output allows easy interfacing to a wide variety of small battery-powered CTDs and loggers.
