Temperature & Dissolved Oxygen TDO-2050

RBR's small, self-contained, submersible Temperature and Dissolved Oxygen logger (sonde, recorder), the TDO-2050, is designed to measure temperature and dissolved oxygen. It's high accuracy and small size (265mm x 38mm OD) makes it useful for many applications. The TDO-2050 can be mounted on the sea or harbour floor, fastened to an existing structure, attached to a mooring line, or used for profiling. It may also be used for freshwater and aquaculture applications. The TDO-2050 is available in two casings, plastic and titanium. The depth rating of the plastic case is 740m, the titanium 2,000m (limited by the dissolved oxygen sensor).

The temperature channel of the TDO-2050 is calibrated to an accuracy of ± 0.002°C (ITS-90). Based on long-term tests the drift has been measured at better than 0.002°C/year. The standard thermistor has a time constant of <3 seconds; a fast thermistor probe is also available (0.095 sec). The dissolved oxygen channel is calibrated to an accuracy of 1% O2 Saturation. Calibration constants are stored in the logger and recalibration is easily carried out by the end-user.
