The DMA672.5 is a precise and reliable sensor for continuous meteorological measurements of air temperature and relative humidity, even under extreme climatic conditions. Designed for use with a radiant shield, it features Pt100 output for temperature and 0–1 V DC output for humidity, ensuring stable, accurate readings in environments with significant thermal and hygrometric variations.
The DMA672.5 Air Temperature and Relative Humidity Sensor is engineered for professional meteorological applications, offering exceptional accuracy and stability. Designed for continuous monitoring, it operates reliably in harsh weather conditions, including strong thermal and hygrometric fluctuations. The sensor must be installed in an anti-radiant shield, with options for natural or forced ventilation, ensuring accurate and consistent data collection.
