Overview

The MaxiMet Marine GMX560 is a high-performance, compact weather station designed for marine environments. It measures wind speed and direction using ultrasonic sensors, along with temperature, humidity, barometric pressure, and includes a 6-axis compass and optional GPS for true wind calculations. With IP66 protection, no moving parts, multiple output protocols (RS232, RS485, Modbus, NMEA, SDI-12), and low power consumption, it is ideal for ships, buoys, offshore platforms, and harsh coastal applications.

Typical applications

Marine environments including Marine buoys, Unmanned surface vessels
Helidecks
Offshore wind farms
Low power deployments and IoT applications

Key Features

MaxiMet Marine GMX560 provides 5 measured parameters: Wind speed & direction, temperature, humidity, pressure, optional heating, optional GPS function
