SBE 37-IMP-ODO MicroCAT CT(D)-DO
The SBE 37-IMP-ODO pumped MicroCAT is a high-accuracy conductivity and temperature (pressure optional) recorder with integrated Inductive Modem (IM) interface, internal batteries, memory, integral Pump, and Optical Dissolved Oxygen. The MicroCAT 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 and derived variables (salinity, sound velocity, specific conductivity) are output in engineering units.
Memory capacity exceeds 380,000 samples. Battery endurance varies, depending on sampling scheme and deployment temperature and pressure. Sampling every 15 minutes (10 °C, 500 dbar), the MicroCAT can be deployed for 8.5 months (24,000 samples).
