Introduction: The water quality automatic sampler is widely used in pollution sources, sewage treatment plant import and export, and online use with COD, ammonia nitrogen, total phosphorus, total nitrogen, heavy metals and other online monitors. The designed flow tracking sampling mode can automatically adjust the sampling flow according to the instantaneous flow, realize continuous sampling, and ensure that the collected water samples are more representative. It has the functions of AB barrel mixed sample supply, automatic emptying of reserved sample bottles, automatic addition of preservatives to reserved water samples, etc. It is an ideal supporting equipment for the online monitoring system of water pollution sources and the overall solution for total emission reduction. Features: 1. Sampling function: It can realize various sampling trigger methods such as timing sampling, time proportional, flow proportional, flow tracking, external control sampling and serial port control; 2. Sample retention function: It can realize out-of-standard sample retention, synchronous sample retention, direct sample retention, and serial port control sample retention; 3. Sample supply function: It can provide continuous mixed water samples to multiple online monitors such as COD, ammonia nitrogen and heavy metals at the same time; artificial comparison 4. Sampling port: with manual sampling port, it can realize the manual comparison function of mixed water samples ; 5. Records: with sample records, door opening and closing records, power failure records and alarm records; 6. Power-off protection: automatic protection after power-off, automatic recovery after power-on; 7. Remote control (optional): It can realize remote status query, parameter setting, record upload, remote control sample retention, etc.; 8. Digital temperature control: precise digital temperature control of the refrigerator, with the addition of a soaking system, the temperature is uniform and accurate; 9. Automatic rinse: before each sampling, rinse the pipeline with the water sample to be tested to ensure the representativeness of the retained sample; 10. Automatic emptying of the mixing barrel: The mixing barrel has the function of fast automatic emptying; 11. Automatic emptying: can realize automatic emptying of water samples in pipelines and sampling bottles; 12. Cleaning function: The sampling pipeline and sampling bottle can be automatically cleaned before each sampling to ensure that the samples collected each time will not interact with each other. Technical parameter: Sampling bottle: Specification: 1000ml × 25 bottles Single sampling volume: 10ml~1000ml Sampling interval: 1min~9999min Sampling records: 10000 Open and close records: 2000 Power outage records: 2000 Sampling error: ±7% Equal-proportional sampling error: ±8% System clock time control error: Δ1≤0.1% Δ12≤30s Water sample storage temperature: 2℃～6℃ (±1.5℃) Sampling vertical height: ≥8m Horizontal sampling distance: ≥80m Air tightness of piping system: ≤-0.085MPa Insulation resistance: ＞20 MΩ Communication interface: RS-232/RS-485 Analog interface: 4mA～20mA Digital input interface: switch
