Catering for the needs of industry and meteorology

Vaisala Instruments manufactures instruments for the measurement of relative humidity, dewpoint, barometric pressure, carbon dioxide, oxygen, wind, cloud height, visibility and present weather. In 2007, operations were organized according to product lines.

Industrial instruments

The product offering is comprehensive, and includes both fixed as well as portable models. Most of the instruments are configurable. The customer chooses the desired functionalities and the probe suitable for their application. The equipment is delivered to the customer ready configured.

Relative humidity measurement equipment is required in many industrial drying processes, such as in paper and timber industries. Optimal humidity conditions improve productivity and product quality, and reduce energy consumption and maintenance costs. Monitoring moisture in oil helps to prevent corrosion and machinery failures.

Dewpoint measurement equipment is used in industries where the formation of dew can be a problem or where it is important to know the precise water content of air or gas.

Carbon dioxide measurement equipment is used for controlling carbon dioxide levels. This is important in industry process control, commercial greenhouses, ecological applications as well as in indoor ventilation control.

Oxygen measurements are used in, for example, combustion and oxidation process control. Pharmaceutical and biotechnological applications in fermentation and bioprocesses are also common, as well as use in gasworks and shielding gas control.

Barometric pressure measurement equipment is used for weather observations in particular. In addition to this, barometric pressure is measured in industrial applications, such as engine performance testing equipment.

Meteorological instruments

Wind and visibility measurement equipment can be used in different weather observation applications. The instruments are used in e.g. shipping and traffic as well as air quality control and agriculture.

Optical visibility sensors are used at airports and runways, for road and waterway weather visibility measurements, and as additional components in weather stations.

Cloud height measurement equipment is used for cloud height and vertical visibility measurement. Their most common applications include airports and different meteorological applications.

The weather transmitter is a compact and easy-to-use station that measures temperature, humidity, pressure, wind speed and direction, and precipitation. It is used in sectors where daily weather data plays a significant role in operations, including agriculture, boat marinas, and ski resorts.
