Environmental research
Environmental research requires accurate measurements. Vaisala's multi-sensor instruments, such as the weather transmitter, are ideal for building dense measurement networks for meteorological and ecological research needs.
Vaisala Combined Pressure, Humidity and Temperature Transmitter PTU300
Measures humidity, temperature, and barometric pressure in two accuracy classes. The PTU300 series features a large numerical and graphical display. Optional data logging and (W)LAN interface.
Vaisala BAROCAP® Digital Barometer PTB210
Excellent solution for outdoor installations. Operates in a wide temperature range. The housing provides IP65 (NEMA4) compliant protection against sprayed water.
Vaisala CARBOCAP® Carbon Dioxide Probe GMP343
Accurate and rugged probe-type instrument for ecological measurements. Diffusion based design - no sampling systems needed. A flow-through model is also available.
Vaisala HUMICAP® Humidity and Temperature Transmitter Series HMT330
Top-of-the-line model for demanding industrial applications. A large numerical and graphical display. A fully configurable transmitter. Optional data logging and (W)LAN interface.
Vaisala Weather Transmitter WXT520
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 WINDCAP® Ultrasonic Wind Sensor WS425
Provides the most accurate and maintenance free wind measurements for demanding applications. Ideal for replacing mechanical sensors.
Vaisala WINDCAP® Ultrasonic Wind Sensor WMT52
Designed for demanding applications where stable and inexpensive wind measurements are required. Optional heating available. Virtually maintenance-free. Suitable for marine, wind energy, and environmental applications.
