2、 Product Overview

This instrument is a new type of water quality automatic sampling equipment carefully designed and built by our company based on ten years of experienceIt has multiple sampling methods such as quantitative, timed quantitative, timed flow quantitative, timed proportional, remote sampling, and excessive retention of samples. It can be widely used in various applications such as enterprise sewage, industrial parks, municipal management, surface water, etc. It can be used as a powerful tool for environmental supervision monitoring, environmental law enforcement monitoring, and analytical instrument comparison.

Different from conventional water sampling equipment, this device can achieve remote automatic emptying function, providing selective sample retention analysis function for regulatory departments, greatly reducing the sampling workload of regulatory departments.

3、 Main features

1Automatic emptying function: Different from "pipeline"+Electric valve "emptying method, this product adopts" automatic turntable "+The "lifting mechanism" emptying method has a simple pipeline, compact structure, few fault points, and a large number of sampling bottles（24A series of advantages such as bottles;

2Remote emptying mode: It can achieve remote single bottle and multi bottle emptying functions through the monitoring platform, enabling selective sample monitoring for regulatory departments and greatly reducing the workload of on-site maintenance;

3Multiple sampling modes: It has multiple sampling modes such as quantitative, timed quantitative, timed flow quantitative, timed proportional, excessive sample retention, remote sampling, etc., which can meet different environmental sampling supervision requirements;

4Excessive sample retention: Adopting innovative integrated water quality excessive sample retention technology, the design of the buffer water tank ensures that the water sample taken for excessive sample retention is the same as the water sample taken for instrument analysis, fully ensuring the representativeness of the excessive sample retention;

5Automatic addition of preservatives (optional): Supports3The automatic addition of different preservatives ensures the representativeness of the samples;

6Security function (optional): Supports access control card swiping and door opening function, fully ensuring the safety of the sample; The system can automatically record and upload door opening information;

7Adopting industrial grade real-time operating system, with fast response time, stable operation, and strong scalability;

8The instrument has a high degree of intelligence and is equipped with real-time network communication interfacesRS232andRS485Accept information from the upper computer or designated control device to achieve remote sampling settings, execution, and response functions;

9The device has power-off protection function, data is not lost, and can be optionally selectedUPS；

10The sampling bottle box has a large volume and maintains a constant temperature throughout the year4±2Within the temperature range of ℃;

11When the instrument performs a single sampling, the sampling volume and number of sampling bottles can be freely set, providing higher flexibility;

12Optional water storage device（5L）Once formed, easy to install and disassemble, with high pressure resistance, easy to observe and clean from the instrument, smooth inner wall, no residual liquid accumulation, and built-in in the refrigerator for low-temperature storage, ensuring that the sampling water does not deteriorate;

13The sampling structure is tightly designed, the sampling and filling action is accurate and stable, the pipeline design is novel, and the back blowing design before and after sampling is adopted. The sampling pipeline has no residual sewage liquid, ensuring that the sample is pollution-free and authentic;

14Implement water and electricity separation, completely separate the control part from the mechanical water intake part, and improve the safety and stability of the instrument;

15The strong and weak electrical components are separated, and the layout of electrical control components is more reasonable, with large space, good heat dissipation, less impact on instrument transmission signals, and easier maintenance. The strong electrical component has high safety.
