    Overview

    		 
       

      The Vaisala HydroMet™ Automatic Weather Station MAWS201 is a portable AWS for temporary installations, featuring the same design as the Vaisala TacMet Tactical Meteorological Observation System MAWS201M for demanding tactical meteorological applications. Its lightweight aluminium tripod and easy-to-use connectors make it fast to set up. Each leg is adjustable for use on uneven terrain. The MAWS201 is field-proven in a wide range of applications:

      • Meteorological research
      • Civil defense
      • Environmental impact studies
      • Emergency response
      • Fire weather
      • Waste management

      The basic suite of sensors typically measures wind, pressure, temperature, relative humidity, and precipitation. In addition, measurements can be taken of e.g. multi-level soil temperature, soil moisture, global and net solar radiation, water level, and temperature. Generic and configurable 16 bit A/D conversion is included in case you want to interface your own sensors. In addition to the standard meteorological and statistical calculations, the extended calculation library also includes evapotranspiration, heat index, forest fire index, wind chill and many others.

      With 5 basic sensors, a solar panel and an internal battery the MAWS201 weighs just 15 kg. It can be transported in two lightweight carry cases made of cellular polypropylene (EPP), a lightweight but very rugged material that provides excellent protection. The cases are equipped with handles, hinges, wheels and latches for padlocks.
