The SBE 37 MicroCAT is a high-accuracy conductivity, temperature, and optional pressure recorder with an integrated Inductive Modem (IM) interface, internal batteries, memory, optional pump, and optional optical dissolved oxygen sensor. The MicroCAT is designed for long-duration deployments on moorings.
Memory capacity can store over 530,000 samples. Sampling every 2 minutes, the MicroCAT can be deployed for 2 years--the battery endurance exceeds memory capacity.
