Project Description
WM-806B High-Performance Automatic Water Sampler
Automatic Water Sampler Application Overview
The automatic water sampler is mainly used for supporting the use of automatic water quality monitoring stations in river sections and drinking water sources.
The automatic water sampler accepts on-site industrial computer control and integrates with various online monitoring wired monitors to coordinate work.
When there is abnormal monitoring or special sample retention requirements, the backup water sample is automatically saved and stored in low temperature refrigeration, which is a necessary part of the automatic water quality monitoring station.
Automatic Water Sampler Features
Regular sampling：timing, time ratio, flow ratio, liquid level ratio, external control sampling.
Bottle separation method: parallel sampling, single sampling, mixed sampling and other methods of bottle separation.
Synchronous sample retention: synchronous sampling and retention samples with online monitor, often used for data comparison.
Remote control (optional): it can realize remote status query, parameter setting, record upload, remote control sampling, etc.
Power failure protection: power-off automatic protection, power-on automatically resume work.
Record: with sampling records.
Low temperature refrigeration: compressor refrigeration.
Automatic rinse: before each sampling, rinse the pipeline with the water sample to be tested to ensure the representativeness of the retained sample.
Automatic emptying: after each sampling, the pipeline is automatically emptied and the sampling head is blown back.
