Core technology

This instrument is a sampling instrument specifically designed for collecting cloud, mist, and water samples in the atmosphere. This instrument has an independently developed cloud and fog detection system and intelligent controller, which realizes the automation of the sampling process and solves the problem of storing and transmitting meteorological parameters during the sampling process.Its technical indicators basically meet the requirements of unmanned operation in the process of cloud-water sample collection, and have been greatly improved in small portability, stable flow and on-site installation, which greatly reduces the labor intensity of sampling. The samplers are made a radical change in terms of material, size and appearance, which greatly improves the collection rate and efficiency of cloud-fog water.

Core technology

This product is jointly developed by the scientific research team of Shandong University and Renhe Zhihai Intelligent Technology (Shandong) Co. Ltd. It is manufactured by Renhe Zhihai Intelligent Technology (Shandong) Co., Ltd. The cloud-fog online automatic monitoring instrument senses clouds and mist through sensors. The cloud-fog water collector of the system automatically collects cloud and mist samples and transports the collected samples to the detection system through pipelines. The detection system automatically measures the pH value, conductivity, and dissolved oxygen of cloud and mist samples, and records and stores relevant measurement data. The computer in the observation room communicates with the system to form a complete record of cloud and mist observation data .
