Thygan - Model VTP37 -Airport Ventilated Thermohygrometer - Weather Station
FromMeteolabor AG
VTP37 is a combination of the WMO-recognized thermohygrometer THYGAN VTP6 and the control unit CU-VTP. The combination of these two instruments saves space, is lighter, and reduces installation efforts. The Thygan is an extremely precise, heated and networked weather station with a dew point mirror. It is designed for low-maintenance use under the most adverse climatic conditions. The VTP37 is both a ventilated, heated thermometer and a dew point mirror hygrometer. The instrument is designed for field operation and meets the highest standards with regards to reliability and accuracy, even under the most severe environmental conditions.

Features include the following:
- Cyclical operation which allows automatic control and regulation of the most important functions. The VTP37 measures the air temperature and dew point approximately 10 times within 40 seconds every ten minutes, [he instrument reports average values along with their standard deviations, allowing you to
- confirm the quality of the data.
- Option to switch from operation in intervals to continuous operation.
- The elimination of negative influences such as moisture (psychrometric effect), radiation, icing, wind, and electromagnetic interference (from radio transmitters).
- Automatically regulated mechanical cleaning of the dew point mirror so no manual maintenance is required.
- The VTP37 has a MeteoBus interface (12 V DC, 48 V AC, RS485).
- Automatic differentiation between ice and water film accumulated on the mirror. The type of deposit is automatically distinguished in the calculation of the relative humidity.
- A software command allows you to choose if you want the humidity measurements as relative humidity over water or as a dew point/frost point.
- The thermometer alerts the user of irregularities such as icing, power supply failures, necessary maintenance, etc.
- VTP37 uses the exact same measurement system as the VTP6, which is recommended as a working reference by the World Meteorological Organization (WMO).
