The SBE 37-SIP pumped MicroCAT is a high-accuracy conductivity and temperature (pressure optional) recorder with Serial interface (RS-232 or RS-485), memory, and integral Pump. Externally powered, it can be used for moored applications requiring fast sampling. The MicroCAT is useful as a stand-alone monitoring device and is easily integrated with other instrumentation platforms.

Data is output in real-time and can be recorded in memory; memory capacity exceeds 530,000 samples. Measured data and derived variables (salinity, sound velocity, depth, density) are output in engineering units.
