Model 6501V-H and 6539B
With the world becoming increasingly sensitive to weather and climate, it is important to measure the weather accurately. The Weather Transmitter 6501V-H offers a six-in-one solution to measure barometric pressure, humidity, precipitation, temperature, and wind speed and direction – all with one instrument!
Compact and lightweight, the 6501V-H is suitable for weather stations, dense networks, buildings, golf courses, marinas, harbors, and hotels – almost anywhere where real time weather data is needed. Accurate and reliable data provided to you early enough can increase safety to life and property.
To measure wind speed and direction, the 6501V-H has the Vaisala WINDCAP® sensor that uses ultrasound to determine horizontal wind speed and direction. The array of three equally spaced transducers on a horizontal plane is a Vaisala specific design, which ensures accurate wind measurement from any horizontal wind direction without blind angles and corrupted readings.
Barometric pressure, temperature, and humidity measurements are combined in the PTU module using capacitive measurement for each parameter. It is easy to change the module without any contact with the sensors.
The Humicap® Humidity & Temperature Probe 6539B is designed for humidity and temperature measurements. It is very accurate, has excellent long-term stability and negligible hysteresis.
The probe’s small diameter allows it to be used in applications with space restrictions, for example, shipping containers or between planks in timber drying kilns. It can also be used in conjunction with the Model 6704A Radiation Gill Screen & Mount in standalone situations.
