Vaisala HMT330MIK is designed to tackle the challenge of accurate humidity measurement in weather observations, especially when dew formation occurs. It allows the outdoor installation of the Vaisala HUMICAP Humidity and Temperature Transmitter HMT337 for reliable meteorological measurements. Both PTU307 and HMT337 solve the dew formation issue by warming the probe, keeping the humidity inside below the ambient level. This ensures precise calculation of the ambient dew point using accurate temperature measurements. Additionally, an extra probe measures ambient temperature to help the transmitter calculate ambient relative humidity based on dew point and temperature values.
