Moored Temperature and (optional) Pressure, at user-programmable intervals. Internal memory and battery, Inductive Modem (IM) interface.
The SBE 39plus-IM is a high-accuracy, fast-sampling temperature (pressure optional) recorder with integrated Inductive Modem (IM) interface, internal batteries, and memory. The 39plus-IM is designed for long-duration deployments on moorings.
Data is recorded in memory and can be transmitted when polled through Inductive Modem telemetry. Measured data are output in engineering units. Memory capacity exceeds 9.5 million samples without pressure, or 5.5 million samples with pressure. Battery endurance varies, depending on the sampling scheme, but the 39plus-IM is usually limited by its memory capacity. Sampling every 7 seconds (without pressure) or 12 seconds (with pressure), the 39plus-IM can be deployed for 2 years.
