The humidity and temperature measuring transmitters offer even greater possibilities for compensating the specific sensor characteristics thanks to state-of-the-art digital microprocessor technology. New standards are set in terms of accuracy, temperature stability, and functionality. Due to various designs, such as for wall or duct mounting, with remote sensor tube or radiation hood, 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.
