SWR-1 Sea Wave Recorder (Silver)

The Steamrock SWR-1 sea wave recorder detects and records changes in sea surface conditions. It displays current significant wave height, a graph showing changes in that wave height for swell and wind waves over time, and apparent wave period and its changes. In addition, the maximum wave height and magnitude of accelerations are detected and recorded.

The device analyzes the boat motion during measurement interval and calculates the wave height and period for this interval, whose duration depends on the chosen timescale.

Results are shown on a high contrast sun readable e-paper display and stored in a built-in memory. The Steamrock SWR-1 is a standalone device that does not require software updates, an internet connection, or an external power supply. It operates on three AA batteries, with the remaining charge displayed using a battery icon and percent number.
