Overview

The AQUAlogger® 530WTD is a wireless temperature and depth data logger designed for reliable performance in both marine and freshwater environments. Compact, robust, and built for demanding applications such as commercial fishing, oceanographic research, and environmental monitoring, it delivers accurate temperature and depth measurements without the need for cables.

Once retrieved from the water, the logger transfers stored data wirelessly to a designated PC or laptop. Its quick, easy setup and deployment save valuable time in the field, making it ideal for repeat profiling, multi-vessel operations, and other projects that require efficient, high-quality data collection.
