Model TDR-2050
Submersible Temperature & Depth Recorder

The TDR-2050 is a small (235mm x 38mm OD), self-contained, submersible temperature and depth recorder (sensors and data logger). It can be deployed for a period of up to three years and can collect more than 1,200,000 sets of samples. Data can be retained in memory for 20 years (even without batteries).

• TDR-2050 clock accuracy of ±32 seconds per year.

• Three year deployment on one set of batteries

• 2,400,000 readings on one set of batteries

The TDR-2050 is available in two casings, plastic and titanium. The depth rating of the plastic case is 740m, the titanium 6,600m (limited by the pressure transducer). The temperature channel of the TDR-2050 is calibrated to an accuracy of ± 0.002°C (ITS-90) over the range -5 to +35°C.  Extended range calibrations are available. Typical drift has been measured to be 0.002°C/year. The thermistor may be external (<3sec time constant) or internal (<20sec time constant). A fast thermistor probe (0.095sec) is also available. The depth channel is calibrated to an accuracy of 0.05%fs  Ranges from 10m to 6,600m are available.
