The humidity and temperature measuring transmitters offer even greater possibilities for compensating specific sensor characteristics, thanks to state-of-the-art digital microprocessor technology. New standards are being set in terms of accuracy, temperature stability, and functionality. Due to various designs, such as wall or duct mounting, with a remote sensor tube or with a radiation shield, as well as an allowable operating temperature for the electronics of -25 to +50 °C (sensor: -40 to +120 °C), the types GHTU-MP and GRHU-MP can be used for nearly all applications.
