DR-803K water quality automatic sampler (mixed supply type

　　Application Overview

The DR-803K water quality automatic sampler is a specially designed and produced sampler by Derun Houtian for the mixed supply and excessive retention of water pollution source online monitoring systems. This 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. Design a flow tracking sampling mode that 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 the function of mixing A and B buckets, and can provide uninterrupted mixed water samples to online monitoring devices.

This water quality automatic sampler can provide uninterrupted mixed water samples to online monitoring devices, enabling the collection of mixed water samples, mixing and temporary storage of mixed water samples, retention and alarm for exceeding standards, refrigeration of samples, automatic cleaning and emptying of mixing buckets, and protection of samples. It meets the requirements of national environmental protection standards such as HJ353-2019, HJ354-2019, HJ355-2019, HJ356-2019, and is an ideal supporting equipment for the overall solution of online monitoring systems for water pollution sources.

　　Features

Sampling function: It can achieve multiple sampling triggering methods such as timed sampling, time ratio, flow ratio, flow tracking, external control sampling, and remote start;

Sample retention function: It can achieve functions such as excessive sample retention, synchronous sample retention, direct sample retention, and serial port control sample retention;

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

Manual comparison sampling port: equipped with a manual sampling port, it can realize the manual comparison function of mixed water samples;

Record: It can record the bottle number, retention time, retention amount, sampling mode, retention mode, retention times, parallel sample number, COD value, NH3-N value, total phosphorus value, and total nitrogen value of each retention sample, and can record 10000 data records;

Power outage protection: Automatic power outage protection, parameters will not be lost after power outage, and the instrument can automatically restore its original working state after power on;

Remote control (optional): It can achieve remote reset, remote start sampling, remote parameter modification, remote extraction of sample records, and can also actively upload sample records. It can also customize communication protocols for users;

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

Automatic rinsing: Before each sampling, rinse the pipeline and sampling bucket with the water sample to ensure the representativeness of the retained sample;

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

External pump control: directly control the external pump to extend the sampling distance;

Preservation agent addition function (optional): The automatic addition of preservation agent function can be added according to customer needs;

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