MaxiMet GMX552

Weather station with black globe sensor

 

  • Compact heat stress monitoring station
  • Weather station for agriculture heat stres
  • Low maintenance weather station with WBGT

The MaxiMet GMX552 is a compact, integrated weather station developed by Gill Instruments, notable for being the world’s first to incorporate a black globe sensor for heat stress monitoring. This feature enables real-time calculation of the Wet Bulb Globe Temperature (WBGT), a critical metric for assessing heat stress in various environments, including agriculture, construction, military training, and public events.

In addition to the black globe sensor, the GMX552 measures standard meteorological parameters such as wind speed and direction, ambient temperature, humidity, and atmospheric pressure. It also offers optional GPS integration for enhanced data accuracy and geolocation. The station is designed for low maintenance, operates efficiently in low-power modes, and is suitable for deployment in outdoor settings.

This model is particularly beneficial for applications where monitoring heat-related stress is crucial, providing accurate and timely data to inform safety measures and decision-making processes.

  • Construction sites and other harsh working conditions
  • Sports events
  • Control systems for manufacturing, agriculture and industry
  • Reporting systems for transport and safety
  • Low power/solar powered deployments and IoT applications
  • Six measured parameters: Black globe temperature, wind speed & direction, temperature, humidity, pressure, optional GPS function
  • Outputs WBGT in accordance with ISO 7243:2017 (up to 70°C)
  • Multiple additional derived parameters
  • Wet bulb sensor can be added for increased accuracy
  • 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
  • Early identification of dangerous working conditions increases worker welfare, reduces risk of sickness and supports long-term productivity
  • 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
