DR-803N water quality automatic sampler (mixed sample supply from

Application Overview

This water quality automatic sampler is widely used in pollution sources, sewage treatment plant imports and exports, and is used in conjunction with online monitoring devices for COD, ammonia nitrogen, total phosphorus, total nitrogen, heavy metals, etc. The designed flow tracking sampling mode can automatically adjust the sampling flow based on instantaneous flow, achieving continuous sampling and ensuring that the collected water samples are more representative. It has functions such as AB bucket mixed sample supply, automatic emptying of sample bottles, and automatic addition of protective agents to retained water samples. It is a supporting equipment for online monitoring systems of water pollution sources and overall solutions for total emission reduction.

This water quality automatic sampler is capable of collecting mixed water samples, mixing and temporarily storing mixed water samples, retaining samples exceeding the standard and triggering alarms, refrigerating samples, automatically cleaning and emptying the mixing bucket, automatically adding fixatives, extending sample storage time, and protecting samples. Compliant with HJ35X-2019 series standards, it is a supporting equipment for the overall solution of online monitoring system for water pollution sources.

Features

1) Sampling function: It can achieve various sampling triggering methods such as timed sampling, time proportional sampling, flow proportional sampling, flow tracking, external control sampling, and serial port control;

2) Sample retention function: It can achieve over standard sample retention, synchronous sample retention, direct sample retention, and serial port control sample retention;

3) Sample supply function: It can simultaneously provide uninterrupted mixed water samples to multiple online monitoring instruments such as COD, ammonia nitrogen, heavy metals, etc;

4) Manual comparison: Equipped with a manual sampling port, it can achieve manual comparison of mixed water samples;

5) Records: with sample retention records, door opening and closing records, power outage records, and alarm records;

6) Power outage protection: automatic power outage protection, automatic power on restoration work;

7) Remote control (optional): It can realize remote status query, parameter setting, record uploading, remote control sample retention, etc;

8) Digital temperature control: digital temperature control for refrigerated containers, equipped with a uniform heating system, ensuring even and accurate temperature distribution;

9) Automatic rinsing: Before each sampling, rinse the pipeline with the water sample to be tested to ensure the representativeness of the retained sample;

10) Automatic emptying of mixing bucket: The mixing bucket has a fast automatic emptying function;

11) Automatic emptying: It can achieve automatic emptying of pipelines and sampling bottles for water samples;

12) Cleaning function: The sampling pipeline and sampling bottle can be automatically moistened and cleaned before each sampling to ensure that the collected samples do not interfere with each other;

13) Automatic addition of fixative: a liquid fixative can be automatically added according to the settings;

14) External pump control: Directly control the external pump to extend the sampling distance.

15) Pipeline optimization: The sampling and supply pipeline is made of hard PVC material to ensure the effectiveness and timeliness of water sample collection.
