Instrument Description

The instrument complies with the requirements of the Chinese Ministry of Environmental ProtectionHJ/T 372-2007The "Technical Requirements and Testing Methods for Water Quality Automatic Samplers" is a multifunctional environmental monitoring instrument that integrates flow measurement, water sample collection, automatic bottle separation, and constant temperature refrigeration. It has the characteristics of small size, easy mobility, simple operation, environmental protection, and energy saving. Suitable for environmental monitoring stations, supervisory agencies, research institutes, water affairs, municipal and sewage treatment plants at all levels, automatic sampling of water samples from industrial pollution source discharge outlets, rivers, lakes, seas, etc.

Main functional features

1. Humanized program design, large screen Chinese display, rich and friendly human-machine dialogue interface, easy and fast operation;

2. By using an input type liquid level sensor or ultrasonic sensor, flow measurement and liquid level measurement can be achieved, completing proportional, timed, fixed flow, liquid level proportional, and quantitative sampling;

3. Multiple sampling functions: timed quantitative sampling, fixed flow quantitative sampling, flow ratio sampling, liquid level ratio sampling, real-time quantitative sampling, etc;

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, includingRS232、4-20mASwitching signals, 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. Equipped with refrigeration function, the sample can be refrigerated at a constant temperature, and the temperature can be set; The refrigeration system has a vehicle mounted power interface, which is convenient for field applications;

8. Equipped with access control function and two-level password locking for parameters to prevent illegal operations;

9. Equipped with automatic recording function for opening and closing doors, it 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, pollution-free liquid and pipeline contact, high temperature resistance, and corrosion resistance;

12. Modular program structure, multipleCPUControl circuit, programmable control, optoelectronic isolation, improve the comprehensive performance of the product;

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

14. Control the bottle splitting device to automatically package samples, with accurate and reliable automatic positioning. 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.
