Small-sized Automatic Sampling Vessel SS30 is used for routine standardized water sampling. Its small size and light weight makes it easy to carry and transport, allowing it for fast and convenient daily operation. It is composed of the sampling boat and a handheld terminal. SS30 can perform standardized water sampling with maximum capacities of 8L. A report will be generated automatically after each mission. The handheld terminal can be used to remotely control the boat or to monitor its working status. Besides, with the optional base station, the sampling mission can be edited and the sampling data can be stored in the database.
