The KDWS-14 SF6 micro water measuring instrument is currently a high-quality replacement product for humidity measurement. It embodies new technology and design from the core to the appearance. The KDWS-14 intelligent micro water measuring instrument was jointly developed by senior engineers from Wuhan Kaidi Zhengda Electric Co., Ltd. and technical forces from universities, and has been recognized by experts and users.

The KDWS-14 SF6 micro water measuring instrument adopts the Vaisala DRYCAP (R) humidity sensor, which has the advantages of high accuracy, good repeatability, fast testing speed, and small drift. It is the choice for industrial environments with low dew point and the need to control dry point. It has a chemical removal option, which enables the product to perform precise and stable measurements in environments with high concentrations of chemicals and cleaning agents, ensuring accurate measurements between each calibration interval.
