WSH-500 Weather Station (Combined and Compact)

Make: Schelt Technology

Model: WSH-500

Our WSH series of weather station is a combined sensor having very compact design & construction. It is widely recommended for industrial, educational, solar power plants, architecture, building design & automation etc.

WSH-500 is a five-element multifunctional meteorological sensor. The sensor integrates six meteorological elements such as –

  • Wind speed
  • Wind direction
  • Temperature
  • Relative Humidity
  • Atmospheric pressure

It has the characteristics of compact structure, no moving parts, sturdiness and durability, easy installation, and maintenance-free features. It is aimed at a wide variety of meteorological products. An intelligent sensor specially designed for on-site installation and maintenance.


  • Weather stations
  • Environmental Monitoring
  • Agro-Meteorology
  • Bridge and Tunnel Engineering
  • Hydraulic Engineering
  • Airports, HVAC
  • Construction, Renewable Energy
  • Building Automation


  • Meteorological parameters such as wind speed & direction, temperature, humidity, air pressure, rainfall are measured simultaneously in one single, compact and lightweight instrument.
  • The absence of moving parts minimizes maintenance.
  • High sensitivity for detecting very low speeds, which are not detectable by traditional methods.
  • Fast and easy installation and station.
  • Sensor is not affected by storm, snow, ice and frost.
  • High accuracy of measurement and stable performance.
  • Material of construction is anti – corrosion and anti – electromagnetic radiation.
