Compared to the previous diaphragm galvanic battery type, the reaction speed has increased, and maintenance has become easier.
This is a DO meter from the INFINITY data logger series with a miniSD card recording method. Various measurement settings are possible, allowing for simultaneous observations not only for tethered monitoring but also with your currently used water samplers, CTDs, etc. Thanks to the high-speed response DO sensor, vertical profiles that previously took a long time to measure can now be observed in a short time. There is also a model with a depth sensor, enabling standalone profile observations.
