37-SM MicroCAT C-T(P) Recorder

Product Name:37-SM MicroCAT C-T(P) Recorder
Description:The SBE 37-SM MicroCAT is a high-accuracy conductivity and temperature (pressure optional) recorder with Serial interface (RS-232 or RS-485), internal batteries, and Memory. The MicroCAT is designed for moorings or other long-duration, fixed-site deployments. 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).
