RBRduet³ T.D & RBRduet³ T.D |deep Dual Channel Logger
RBR’s most compact, lightweight, and versatile dual channel logger.
- Standard sampling up to 2 Hz, and optionally up to 32 Hz
- Any AA battery
- USB-C download
- Optional tide, and wave variants
- Cabled RBRcoda³ variant available
Its small compact size is so versatile that it lends itself to various applications from mooring, bore holes, profiling, or towed arrays. The RBRduet³ T.D is the next generation of RBR’s proven self-contained small submersible temperature recorder; the TDR-2050. This two channel submersible temperature and depth logger is ideal for long term deployments, harsh environments or anywhere where size is a concern. While smaller in size to the TDR-2050 or the RBRduo³ T.D, the RBRduet³ uses a completely new architecture resulting in less power consumption, more memory capacity, and faster download speeds.
The RBRduet³ T.D is calibrated to an accuracy of ±0.002ºC (ITS-90 and NIST traceable standards) and accuracy of 0.05% full scale for pressure (between -5º C and 35º C). The standard thermistor has a time constant of approximately 1.0 seconds.
The RBRduet³ T.D has a measurement range of -5º C to +35º C in its standard calibration. However, it can be calibrated from -40º C to +50º C. Contact RBR about your particular measurement range. There are a number of pressure (depth) rating options from 20 dbar to 10,000 dbar.
