Temperature and (optional) Pressure, at user-programmable intervals. Internal memory and battery pack, RS-232 and USB interface. Configurations with internal or external thermistor, external connector, pressure.
The SBE 39plus is a high-accuracy, fast-sampling temperature (pressure optional) recorder with USB interface, internal batteries, and memory. The 39plus is designed for moorings or other long-duration, fixed-site deployments, as well as deployments on nets, towed vehicles, or ROVs.
Data is recorded in memory and can also be output in real-time. Measured data are output in engineering units. Memory capacity exceeds 9.5 million samples without pressure, or 5.5 million samples with pressure. Sampling every 0.5 sec, this yields approximately 55 days of data without pressure or 32 days with pressure (battery endurance exceeds memory capacity).
