Vaisala Radiosonde RS41 offers excellent data availability and accuracy of humidity, temperature, pressure, and wind measurement. The radiosonde is fast and stable with individual, SI-standard traceable calibration.

Vaisala Radiosonde RS41 temperature sensor uses linear resistive platinum technology. The small size of the sensor results in low solar radiation error and guarantees fast response. Wind data, height and pressure are derived from Vaisala Radiosonde RS41 GPS data combined with differential corrected GPS data from the ground station.

Robust design, physical zero humidity check and in-built functional temperature check ensure reliable performance in every situation. The radiosonde is also easy to use. For example, there is no need for the user to connect the batteries to the radiosonde to activate it. The radiosonde is automatically activated when placed on the ground check device. To make it easier to check the status of the radiosonde, the radiosonde has LED light indicators visible on the cover.
