Automatic Water Sampler

1.Automatic Water Sampler Implementation Standards:

HJ/T372-2007 Technical Requirements and Testing Methods for Automatic Water Samplers

HJ 493-2009 "Preservation and management technology of water quality samples"

HJ/91.1-2019 Technical Specifications for Wastewater Monitoring

HJ/353-2019 Technical Specifications for Installation of Online Monitoring Systems for Water Pollution Sources (CODcr, NH3-N, etc.)

2. Scope of application of Automatic Water Sampler:

This product can realize single sampling or continuous mixed sampling of sewage at the discharge port, and provide the mixed sample for analysis by online analysis equipment to realize the monitoring function of mixed sewage samples at the discharge port; at the same time, the product has the function of automatic emptying of remote sampling bottles.

3. Main features of Automatic Water Sampler:

1. A/B double barrel configuration: Equipped with A/B double barrels, it can realize continuous mixed sample collection, instrument sample supply, sample retention for exceeding the standard, and automatic emptying of sampling bottles;

2. Automatic emptying function: Different from the "pipeline + electric valve" emptying method, this product adopts the "automatic turntable + lifting mechanism" emptying method, which has the advantages of simple pipeline, compact structure, few fault points, and a large number of sampling bottles (24 bottles);

3. Remote emptying mode: remote single-bottle and multi-bottle emptying functions can be realized through the monitoring platform;

4. Automatic addition of preservatives: It can support the automatic addition of 3 different preservatives to ensure the representativeness of the sample;

5. Security function: Support electronic access control management function, the system automatically generates passwords, records and uploads corresponding information;

6. Real-time network communication interfaces RS232 and RS485 to realize remote sampling setting, execution and response functions;

7. The sampling bottle chamber has a large volume and the temperature is kept constant at 4±2℃ all year round;

8. The sampling structure is designed tightly, and the pipeline has a backflush design, with no sewage residue, ensuring that the sample is pollution-free and authentic;

9. Separation of water and electricity is implemented, and the control part is completely separated from the mechanical water intake part, which improves the safety and stability of the instrument;

10. Parallel sample function: The product can realize the parallel sample collection function and provide double samples for enterprises and regulatory agencies.

11. Equipped with a manual comparison sampling port for mixed water samples.

12. It has the function of collecting instant water samples.
