MaxiMet GMX600
Measures 6 parameters including precipitation
- Top multi-parameter weather stations 2024
- Best weather station with rain and wind sensors
- Compact weather stations for remote sites
Overview
The MaxiMet GMX600 is an all‑in‑one weather station that combines measurements of wind speed & direction, precipitation, temperature, humidity, and barometric pressure in one rugged unit. It uses ultrasonic wind sensors (no moving parts) and an optical rain gauge for precipitation, with optional GPS for true wind and location data. It supports various digital output protocols (RS‑232, RS‑485, SDI‑12, NMEA, Modbus, ASCII) and offers selectable data rates (1/sec, 1/min, 1/hr) with a low power “eco” mode. The GMX600 is designed for durability, featuring a naturally aspirated, UV‑stable radiation shield, IP66 protection, operation from about ‑40 °C to +70 °C (with heating option), and weighs around 0.8 kg.
Typical applications
- Control systems including smart buildings, agriculture and industry
- Solar farms
- Road and rail
- Ports and harbours
- Reporting systems for transport and safety
- Low power/solar powered deployments and IoT applications
Key Features
- Six measured parameters: Wind speed & direction, temperature, humidity, pressure, rainfall (optical sensor), optional heating, optional GPS function
- Multiple additional derived parameters based on combining measured parameters, such as gust, average wind speed and dew point
- High quality, accurate, solid-state sensors
- 2-axis compass
- Optional integrated GPS capability available to provide location, GPS timestamp and a calculation of true wind if the platform is moving
- Optional low power heating
Benefits
- High quality measurement data due to careful sensor selection and extensive design testing and verification
- Easy to set-up and integrate using comprehensive software to select the reported and derived parameters and measurement units required
- Easy to install and long operational life, due to a compact, robust design and the selection of low maintenance sensors
- Suitable for use with battery or solar systems in low power mode
