What are the classifications and functions of the online water quality automatic sampler

The online water quality automatic sampler is under the control of the instrument, the water sample is quantitatively collected into the sampling bottle through the peristaltic pump according to the set procedure, and the low-temperature refrigeration is completed for analysis in the laboratory. That is to say, the water quality sampler uses a peristaltic pump to collect water samples into the instrument, sends the water samples into the sampling bottle through the instrument distribution system, and keeps the temperature of the water samples at 4°C through the constant temperature system, thereby completing the automatic collection of water samples, Automatic distribution and constant temperature preservation process. Widely used in electroplating plants, slaughterhouses, chemical plants, food plants, steel plants, etc. The online water quality automatic sampler can also retain samples exceeding the standard according to functional needs. According to the sampling function of the water quality sampler, it can be divided into flow equal proportion sampling, timing sampling and remote control sampling, etc. According to whether the samples are stored in separate bottles, it can be divided into bottle-divided water quality samplers and mixed water quality samplers. The functions of the online water quality automatic sampler: Automatic rinse: Before each sampling, rinse the pipeline with the water sample to be tested to ensure the representativeness of the reserved sample; Parallel sampling: The same water sample can be divided into two identical samples at the same time The same water sample can also be packed in different material sampling bottles to meet the requirements of multi-component analysis of the same water sample; Quality control sampling: set a group in separate sampling bottles or multiple groups of parallel samples, and the consistency of the results of the parallel samples proves the reliability of the entire test; Automatic emptying: after each sampling, the pipeline is automatically emptied and the sampling head is blown back; Water sample storage: stored at room temperature; Timely start function: start sampling after the delay time is reached; Power-off protection function: After the instrument is powered off and then powered on again in the running state, the instrument can automatically restore the original running state, and the instrument parameters will not be lost after power-off; Appearance and structure: integrated Type design, easy to carry; sampling record function: with sampling records, door opening and closing records, power outage records.
