It is controlled by the on-site industrial computer, integrated with various online monitoring wired monitors, and works in coordination. When there is abnormal monitoring or special sample retention requirements, the backup water sample is automatically saved and stored in low temperature refrigeration. It is a necessary component of an automatic water quality monitoring station. part.

Technical characteristics

◎Conventional sampling: timing, time proportional, flow proportional, liquid level proportional, external control sampling;

◎Bottle splitting method: parallel sampling, single sampling, mixed sampling and other bottle splitting methods;

◎Simultaneous sample retention: synchronous sampling and retention with the 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-off protection: automatic protection when power-off, automatic recovery after power-on;

◎Records: 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 backflushed.
