Name：Portable Automatic Water Sampler Mixed Collection Type
Model：EJ-BX12
Description：
EJ-BX12 type (portable mixed collection type) automatic water sampler is a dedicated environmental monitoring instrument used for surface water and wastewater sampling, the monitoring of water sources, pollution source investigation and total control. It adopts the internationally common peristaltic pump water intake method, and is controlled by a single-chip microcomputer. According to user’s needs, to collect equal proportion mixed water samples and isochronous mixed water samples. Meet the sampling requirements in HJ/T91-2002 "Surface Water and Wastewater Monitoring Technical Specifications" issued by the National Environmental Protection Agency. Using the standard 12V battery to work. In the field, when the battery is insufficient, the car battery can be used instead. It is one of the necessary instruments for the environmental monitoring at all levels, the water pollution monitoring of the supervision station and the research work of the environmental protection and research department.
