The automatic water quality sampler is mainly used for supporting water quality automatic monitoring stations in river sections,drinking water sources etc. It accepts on-site industrial computer control, integrates with online water quality analyzers. When there is abnormal monitoring or special sample retention requirements, it automatically saves backup water samples and stores them in low temperature storage. It is a necessary instrument of automatic water quality monitoring stations.
Technical Features
1) Conventional sampling: time ratio, flow ratio, liquid level ratio, by external control .
2) Bottle separation methods: parallel sampling, single sampling, mixed sampling, etc.
3) Synchronous retention sample: Synchronous sampling and retention sample with online monitor, often used for data comparison;
4) Remote control (optional): It can realize remote status query, parameter setting, record upload, remote control sampling, etc.
5) Power-off protection: automatic protection when power-off, and automatically resume work after power-on.
6) Record: with sampling record.
7) Low temperature refrigeration: compressor refrigeration.
8) Automatic clean: before each sampling, clean the pipeline with the water sample to be tested to ensure the representativeness of the retained sample.
9) Automatic emptying: After each sampling, the pipeline is automatically emptied and the sampling head is blown back.
