The Vaisala CARBOCAP® Sensor is a silicon based, non-dispersive infrared (NDIR) sensor for the measurement of carbon dioxide.

Vaisala provides high quality ceilometers which measure cloud heights at 25,000 feet or 40,000 feet. These sensors offer a superior measurement accuracy which has been documented in international intercomparisons.

Vaisala's relative humidity and air temperature sensors provide excellent accuracy and stability. These products meet even the most exacting demands in meteorology and hydrology.

Vaisala provides a variety of highly accurate rain gauges and precipitation sensors for various of applications.

In the Vaisala present weather detectors you will find the mix you require of visibility measurement range, characterization of reduced visibility, precipitation type identification, precipitation accumulation/intensity measurement, and report formats. Vaisala present weather detectors are a sensor family that grows with your needs.

Vaisala offers instruments for measuring both global solar radiation, net radiation and sunshine duration both in portable and fixed automatic weather stations. Easy interfacing and maintenance characterize all of these sensors.

The Vaisala Weather Transmitter WXT520 measuring the six most essential weather parameters (wind speed and direction, liquid precipitation, barometric pressure, temperature, and relative humidity) in one fully integrated instrument with no moving parts. WXT520 replaces WXT510. Applications include weather stations, dense networks, buildings, golf courses, marinas, harbors, and hotels.

Vaisala offers a versatile product range for wind measurement, comprising wind vanes, anemometers, combined wind sensors and ultrasonic wind sensors, which are available also in heated models.
