Application Overview

DR-803K water quality automatic sampler is a sampler specially designed and produced for the on-line monitoring system of water pollution sources to mix samples and keep samples exceeding the standard. The sampler is widely used in pollution sources, sewage treatment plant import and export, and COD, ammonia nitrogen, total phosphorus, total nitrogen, heavy metals and other online monitoring device online use. The flow tracking sampling mode is designed, which can automatically adjust the sampling flow according to the instantaneous flow, realize continuous sampling, and ensure that the collected water samples are more representative. With A, B barrel mixed sample function, can provide uninterrupted mixed water samples to the online monitor.
The water quality automatic sampler can provide uninterrupted mixed water samples to the online monitor, and realize the functions of collecting mixed water samples, mixing and temporary storage of mixed water samples, over-standard sample retention and alarm, refrigerated samples, automatic cleaning and emptying of the mixing barrel, sample protection, etc. It meets the requirements of national environmental protection standards such as HJ353-2019, HJ354-2019, HJ355-2019, HJ356-2019, etc. It is an ideal supporting equipment for the overall solution of water pollution source online monitoring system.

Features

sampling function: it can realize timing sampling, time ratio, flow ratio, flow tracking, external control sampling and remote start and other sampling trigger modes;
Sample retention function: it can realize the functions of over-standard sample retention, synchronous sample retention, direct sample retention and serial port control sample retention;
Sample supply function: it can provide uninterrupted mixed water samples to multiple online monitors such as COD, ammonia nitrogen and heavy metals at the same time;
Manual comparison sampling port: with manual sampling port, can realize the manual comparison function of mixed water samples;
Record: the sample bottle number, sample retention time, sample retention volume, sampling mode, sample retention mode, sample retention times, parallel sample number, COD value, NH3 -N value, total phosphorus value and total nitrogen value of each sample retention can be recorded, and the latest 10000 data records can be recorded;
Power-off protection: power-off automatic protection, the parameters will not be lost after power-off, and the instrument can automatically restore the original working state after power-on;
Remote control (optional): it can realize remote reset, remote start sampling, remote modification of parameters, remote extraction of sample retention records, and can also actively upload sample retention records, and can customize communication protocols for users;
Digital temperature control: precise digital temperature control of the refrigerator, the installation of a heat system, uniform and accurate temperature;
Automatic washing: before each sampling, wash the pipeline and sampling barrel with the water sample to be tested to ensure the representativeness of the retained sample;
Automatic emptying of the mixing barrel: the mixing barrel has a fast and automatic emptying function;
External pump control: directly control the external pump and lengthen the sampling distance;
Preservation agent add function (optional): according to customer demand to increase the automatic add preservation agent function;
Pipeline optimization: the sampling pipeline is made of rigid PVC material to ensure the effectiveness and timeliness of water sample collection.
