| Definition | 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). Available in two casings, plastic and titanium, with depth ratings of 740m and 6600m respectively. 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. Typical drift has been measured to be 0.002°C per 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. | |
