　　4. Multiple sampling program startup methods: external signal triggered startup, over limit sample retention startup, preset time startup, instant startup, liquid level over limit triggered startup, etc., to meet user needs;

　　5. Multiple external interface methods, including RS232, 4-20mA, switch signal, etc., facilitate connection with other online devices;

　　6. Built in flowmeter function, suitable for flow measurement of industrial pollution source discharge outlets of various types of weirs such as triangular weirs, rectangular weirs, equal width weirs, and Bacher troughs;

　　7. It has a refrigeration function, which can keep samples at a constant temperature and set the temperature; The refrigeration system has a vehicle mounted power interface, which is convenient for field applications;

　　8. It has access control function, with two-level password locking for parameters to prevent illegal operations;

　　9. It has an automatic record function for opening and closing doors, which can query the time when the sample chamber is opened and closed each time;

　　10. Rich data query function, large capacity data storage function, convenient for users to conduct statistical analysis;

　　11. High reliability peristaltic pump, hybrid stepper motor subdivision drive, smooth and reliable operation, easy to disassemble pump head, liquid and pipeline contact without pollution, high temperature resistance, and corrosion resistance;

　　12. Modular program structure, multi CPU control circuit, programmable control, optoelectronic isolation, improve the overall performance of the product;

　　13. Liquid flow detector, automatically completes the cleaning and emptying of the sampling port and pipeline to ensure the collection of qualified water samples;

　　14. Control the bottle splitting device to automatically package samples, with accurate and reliable automatic positioning for packaging. The bottle splitting method can be set to complete single or mixed collection;

　　15. It has an automatic drainage function to meet various water quality conditions and has a pre rinsing function for pipelines.
