1）Timed Sampling: According to the established sampling schedule, the automatic water quality sampler will collect a fixed volume of water samples from the sampling point.In the mixed sampling drum,No Chinese content provided.Discharge or preserve the collected mixed water samples according to the set parameters (sampling settings, retention settings).Place into the sample bottle.

2）Time-proportional sampling: The water quality automatic sampler collects a fixed volume of water sample from the sampling point at the set time intervals.In a mixed sampling drum,AndAccording to the set parameters (sampling settings, retention settings), the collected mixed water samples are either discharged or preserved.Place into the sample bottle.

3）Flow Rate Proportional Sampling: EachNo Chinese content provided.Volume guaranteedNo Chinese content provided.，Automatic Water Quality Sampling DeviceAutomatically transfers quantitative water samples from sampling pointsHarvestThere is no Chinese content provided for translation.In the mixed sampling drum,No Chinese content provided.Discharge or preserve the collected mixed water samples according to the set parameters (sampling setup, retention setup)Place into the sample bottle.

4) Flow Tracking Sampling: The water quality automatic sampler adjusts the sampling rate automatically based on the flow size, continuously collecting water samples from the sampling point.No Chinese content provided.In the mixed sampling drum,AndAccording to the set parameters (sampling settings, retention settings), the collected mixed water samples are either drained or preserved.Please transfer to the sample bottle.

5) External Sampling Control: The water quality automatic sampler receives an external sampling trigger signal (switching quantity signal, IN5) when...Automatic water quality samplers will quantitatively collect water samples from sampling pointsIn a mixed sampling drum,AndAccording to set parameters (sampling settings, retention settings), the collected mixed water samples are either drained or preserved.Please transfer to the sample bottle.

6) Serial Port Control: Upon receiving a serial port (COM3) command, the automatic water quality sampler performs sampling, sample supply, and sample retention as per the command's instructions. Specific sampling volume, sample supply time, sample retention quantity, parallel sample quantity for retention, and bottle number for retention are processed according to the corresponding command parameters.
