SBE 39plus Temperature Recorder
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. Memory capacity exceeds 9.5 million samples excluding pressure data, or 5.5 million samples including pressure. Sampling every 0.5 sec yields approximately 55 days of data without pressure or 32 days with pressure (battery endurance exceeds memory capacity).
