Features & Configurations
The RBRduet3Â T.DÂ provides accurate temperature and pressure measurements during long deployments. Low power consumption, large memory, and ability to endure harsh conditions make it a perfect instrument for many oceanographic applications, including tide levels and wave characteristics.
The RBRduet³ T.D is calibrated to an accuracy of ±0.002ºC (ITS-90 and NIST traceable standards) and and accuracy of 0.05% full scale for pressure (between -5ºC and 35ºC). The standard thermistor has a time constant of approximately one second.
The RBRduet³ T.D has a measurement range of -5ºC to +35ºC in its standard calibration. However, it can be calibrated from -40ºC to +50ºC. Contact RBR about your particular measurement range. There are a number of pressure rating options from 20dbar to 10000dbar.
