1、 Product Overview

The JH-8000A water quality proportional sampler meets the technical requirements and testing methods of the Chinese Ministry of Environmental Protection for automatic water quality samplers (HJ/T372-2007), and has the characteristics of small size, easy mobility, simple operation, environmental protection and energy saving. Suitable for various environmental monitoring stations, supervisory agencies, research institutes, water affairs, municipal and sewage treatment plants, automatic sampling of water samples from industrial pollution source discharge outlets, rivers, lakes, seas, etc.

2、 Performance characteristics

1. Multiple sampling program startup methods: preset time startup, external signal triggered startup, over limit sample retention startup, instant startup, liquid level over limit triggered startup, etc., to meet various user applications.

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

3. Multiple external signal access methods, including 4-20mA signals, 2-channel RS232 signals, RS485 signals, and switch signal interfaces, facilitate online operation with online devices.

4. It has an automatic emptying function for the pipeline, which automatically empties the pipeline after sample collection to meet various water quality conditions. It also has a pre rinsing function for the pipeline to ensure the collection of representative samples.

5. Automatic sample packaging, with a variety of sample packaging methods.

6. Equipped with a remote communication interface, it can remotely control the startup through SMS and remotely check the on-site status (optional).

7. Rich operation record saving function, where every key operation of the user is recorded, facilitating future queries.

8. Rich data query function, large capacity data storage, can store 10000 sampling records, 2000 alarm records, and can query hourly, daily, and monthly traffic data for two years, facilitating user statistical analysis.

9. It has printing and communication functions, and can output on-site data to a computer or printer.

10. Two * password lock, two * management permissions to prevent illegal operations.

11. Liquid sensors detect liquids to improve sample collection accuracy.
