2、 Scope of application:

This product can achieve the discharge of sewage from the outletSingle procurement orcontinuousMixed collectionProvide the mixed sample for online analysis equipment to monitor the mixed sample of wastewater at the discharge outletAt the same time, the product has a remote sampling bottle automatic emptying function.

3、 Main features:

1、A/BDual bucket configuration: configurationA/BDouble bucket, capable of continuous mixed sample collection and instrument sample supply、Excessive retention of samplesAnd automatic emptying of sampling bottlesFunction;

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);

3Remote emptying mode: It can achieve remote single bottle and multi bottle emptying functions through the monitoring platform;

4Automatic addition of preservatives (optional): Supports3Automatic addition of different preservatives to ensure sample representativeness;

5Security function (optional): Supports access control management function,The system automatically generates passwords, records and uploads corresponding information;

6Real time network communication interfaceRS232andRS485Implement remote sampling settings, execution, and response functions;

7The sampling bottle box has a large volume and maintains a constant temperature throughout the year4±2Within the temperature range of ℃;

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

9Implement water and electricity separation, completely separate the control part from the mechanical water intake part, and improve the safety and stability of the instrument;

10. Parallel sample function: The product can achieve parallel sample collection function, providing double retention samples for enterprises and regulatory units.

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