The SBE 37-SM/SMP/SMP-ODO MicroCAT is a high-accuracy conductivity and temperature (pressure optional) recorder with RS-232 or RS-485 interface, internal batteries, data storage, optional pump, and optional optical dissolved oxygen sensor. The MicroCAT is designed for moorings or other long-duration, fixed-site deployments for fully autonomous applications.
Data is recorded in memory and can be output in real-time. Measured data and derived variables (salinity, sound velocity) are output in engineering units.
Memory capacity exceeds 530,000 samples. Sampling every 2 minutes, the MicroCAT can be deployed for 2 years: battery endurance exceeds memory capacity.
