Compact-CT Compact-TD
Overview

The Compact Series instruments are small, highly accurate two-channel recorders for temperature-depth(TD) or conductivity-temperature(CT). Instrument programming and access to the recorded data is easily accomplished with a straightforward Windows software. The self-contained instruments are ideal for long-term moorings for up to two years and integrate easily into your application.
