The RBRsolo³ T with a thermistor-type temperature sensor is our most compact, lightweight, and versatile single-channel instrument. Its small size lends itself to various applications from mooring to bore holes to profiling to towed arrays. It is ideal for long-term deployments, harsh environments, or anywhere where size is a concern. No other temperature logger on the market combines this level of accuracy with the ability to record 130M readings on a single battery. The | fast option provides an additional capability to sample at up to 32Hz.

The RBRsolo³ T is calibrated to an accuracy of ±0.002ºC (ITS-90 and NIST traceable standards). The standard thermistor has a time constant of approximately one second (100ms for the| fast option).

The RBRsolo³ T has a measurement range of -5°C to +35°C in its standard calibration. However, it can be calibrated from -40°C to +50°C. The housing has a depth rating of 1700m, whereas the RBRsolo³ T | deep can go up to 10km deep.
