产品概述
• SS206-04 uses weighing technology and a high-precision sensor to measure precipitation intensity and accumulated precipitation.
• It supports all-type precipitation monitoring, including solid, liquid and mixed precipitation, and can be equipped with an automatic heating option for cold and freezing conditions.
• Low-power operation, convenient installation, low maintenance and simple calibration make it suitable for hydrology, meteorology, emergency response, transportation, agriculture, forestry, power and research applications.
