The low frost point standard humidity generator is one of the essential instruments in humidity calibration. The system is based on the principle of dual temperature and dual pressure method, uses efficient refrigeration constant temperature bath, and adopts advanced pressure and flow control technology to generate a wide range and high accuracy of standard humidity, which can be used for calibration of various types of dew point instruments. The minimum frost point temperature can reach -70 ℃.

This system is widely applicable to the humidity calibration needs of metrology departments and research institutes.

Including the metrology certificate of the National Defense Science and Technology Industry First Metrology Testing and Research Center, the technical indicators meet the requirements of current regulations/specifications.
