2、 Product Overview:

This instrument is a new model carefully designed and crafted by our company based on ten years of experience. It is designed for monitoring surface water stations, national control points, retaining samples of pollution sources exceeding standards, and routine sampling, and is an ideal instrument for remote water quality sampling. It is also an ideal tool for regulatory remote water quality sampling of various sewage treatment enterprises and for measuring and charging for inflow concentration. This product is equipped with automatic dosing and water sample adjustmentPH value function.

3、 Main features:

1Automatic additionPreservation agentFunction: Implement automatic addition to the collected water samplePreservation agentAdjust itPH value function,Preservation agentThe joining method complies withHJ 493-2009 "Preservation and Management Techniques for Water Quality Samples" greatly improves the stability of water sample collection;

2Add preservativeType configurable: The type and amount of reagents required can be flexibly configured according to the different components to be tested in the collected water sample, meeting the dosing requirements for most conventional physical and chemical indicators and heavy metal component analysis;

3addPreservation agentReliability of components: using internationally renowned brand corrosion-resistant additivesPreservation agentPump, ensure to addPreservation agentLong term stable and reliable operation of institutions;

4addPreservation agentComponent security: for addingPreservation agentThe reagent bottle is locked and an alarm is triggered for illegal operations of removing the reagent bottle;

5Insufficient reagent alarm function: When the amount of reagent added is below the set alarm threshold, it can automatically prompt the corresponding alarm information;

6Adopting innovative integrated water quality exceedance retention device technology, compatible with exceedance retention and conventional sampling; Pipeline pressurized water and open non pressurized water sampling;

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

8The instrument control part adopts advanced embedded system design and has strong intelligent sampling function,

According to User sampling requirements,Collect water samples using five sampling methods (including timed and quantitative, timed and quantitative, timed and proportional, quantitative, and exceedance retention), which can be remotely sampled；

9The instrument has a high degree of intelligence and is equipped with real-time network communication interfacesRS232 and RS485, accept information from the upper computer or designated control device to achieve remote sampling settings, execution, and response functions;

10The device has power-off protection function, data is not lost, and can be optionally selectedUPS；

11The sampling bottle box has a large volume and maintains a constant temperature throughout the year4±2℃Within the scope;

12When the instrument performs a single sampling, the sampling amount and number of sampling bottles can be freely set, providing higher flexibility;

13Sampling bottles can be selected24 pieces, capacity 1L, reusableSampling of inert materialsBottles, sampling bottles are arranged in a fan-shaped manner inside a circular box, with a compact structure and a large sampling volume;

14Optional water storage device（5L) one-time forming, 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;

15The sampling structure design is tight, 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;

16Implement water and electricity separation, completely separate the control part from the mechanical water intake part, and improve the safety and stability of the instrument;

17Separation of strong and weak electrical components, more reasonable layout of electrical control components, large space, good heat dissipation, less impact on instrument transmission signals, easier maintenance, and high safety of strong electrical components;

18The excessive sample retention pump is placed inside the samplerGreatly reducing the vibration and noise during sampling, resulting in low noise and vibration during instrument sampling;

19The device has remote door status query and door opening SMS alarm function(Optional), the instrument door is equipped with a sealing device (optional).
