Water thermometer

During a sailing trip, you often wonder what the water temperature is in that particular place. Many modern boats have a water thermometer sensor integrated into a depth sounder. It transmits real-time measurement data either directly to a display or to a data bus. Merisirri stays away from such vanity and instead relies on traditional paraffin-based water thermometer which is both affordable and maintenance-free. Measuring water temperature with an analog thermometer during a sail is as such a social and exciting event.
