The water quality automatic sampler is primarily used in conjunction with automatic monitoring stations for water quality at river cross-sections and drinking water sources. It is controlled by a local industrial control computer and integrated with various online monitoring instruments via wired connections.The unit coordinates operations and, in the event of monitoring anomalies or special sample retention requirements, automatically saves backup water samples and stores them at low temperatures in refrigeration. It is an essential component of an automatic water quality monitoring station. Routine Sampling: timed, proportional to time, proportional to flow, proportional to level, external control sampling. Bottle Splitting Methods: Parallel sampling, single sampling, mixed sampling, etc. Simultaneous Sample Retention: Synchronized with online monitoring instruments for sampling and retaining samples, commonly used for data comparison. Remote Control(Optional): Allows for remote status inquiries, parameter settings, record uploads, and remote control sampling, etc. Power Failure Protection: Automatic protection during power outage, automatic resumption of operation upon power restoration. Record: With sampling records. Low Temperature Refrigeration: Compressor Cooling Automatic Rinse: Rinse the pipeline with the water sample to be tested prior to each sampling to ensure the representativeness of the retained sample. Automatic Emptying: After each sampling is completed, the pipeline is automatically emptied and the sampling head is back-flushed.
