The OTT CTD is a professional data logger that measures water level, temperature and conductivity. Furthermore, it can also output the salinity and the total dissolved solids (TDS).
The CTD saves all measurements in the integrated 4MB non-volatile ring buffer (approx. 500,000 values).
Although especially designed for groundwater applications, the OTT CTD is also well suited for surface measurements
In addition to the proven product characteristics of high-quality pressure probes from OTT, the OTT CTD provides a conductivity measuring cell that meets all the demands of hydrological data collection.
Overall, the OTT CTD has proved to be reliable and rugged. This is ensured by the robust and reliable measuring cells, the high-quality stainless-steel housing, the kevlar-strengthened probe cable with integrated compensating capillary and an ingenious design.
An infrared interface allows the data to be conveniently read out or transferred from the device with a notebook. A well structured, self-explanatory operating program with all the necessary functions for data output and export, configuration and calibration is supplied.
And if remote data transmission is needed, with the
the CTD can easily be equipped for data transmission using GMS/SMS or GPRS.
