SBE-56 Temperature Logger

Sea-Bird Electronics

The SBE 56's pressure-protected thermistor has a 0.5 second time constant, providing excellent accuracy (initial accuracy 0.002 °C) and resolution when fast sampling at 2 Hz (0.5 sec). It has exceptional stability; drift is typically less than 0.002 °C per year. The SBE 56 delivers unprecedented accuracy and stability at a price you would expect to pay for similar recorders that are less accurate.

Before you assume that your application does not require such high accuracy and stability, remember that high stability preserves the initial calibration accuracy and means less frequent (or no) calibrations. For example, if you need only ±0.01 °C accuracy, you will not have to calibrate the SBE 56 for at least 5 years.

The SBE 56 is equipped with 64 MB memory, high-accuracy real time clock, plastic housing for depths up to 1500 meters (4900 ft), and USB 2.0 interface. Calibration coefficients are stored in memory; the included easy-to-use Java-based software (compatible with nearly any computer operating system) uploads the raw data, applies the coefficients, and outputs and plots finished data in degrees C and date and time.
