The DR-803K Water Quality Automatic Sampler is a specialized sampler designed and produced by Derun Hou Tian for mixed sampling and retention of samples exceeding standard levels in online water pollution source monitoring systems. It is widely used at pollution sources and wastewater treatment plant inlets and outlets, and is connected with online monitors for COD, ammonia nitrogen, total phosphorus, total nitrogen, heavy metals, etc. The sampler is designed with a flow tracking sampling mode, which can automatically adjust the sampling flow rate based on instantaneous flow, achieving continuous sampling, and ensuring that the collected water samples are more representative. It features A, BBucket mixing sample function, capable of feeding online monitorProvide uninterrupted mixed water samples.

The water quality automatic sampler can continuously supply mixed water samples to the online monitor, achieving the functions of collecting mixed water samples, mixing them, temporarily storing them, retaining samples exceeding the standard, and triggering alarms.Hidden samples, automatic cleaning and emptying of mixing tanks, and sample protection functions, meetHJ353-2019、HJ354-2019、HJ355-2019、HJ356-2019PendingStandard requirements make it the ideal auxiliary equipment for a comprehensive on-site water pollution source monitoring system solution.

Features

Sample Function: Offers various triggering methods for sampling, including timed sampling, proportional to time and flow, flow tracking, external control sampling, and remote start.

Sample Retention Feature: Allows for exceeding sample retention, synchronized sample retention, direct sample retention, and serial port control sample retention functions.

Sample Function: Can simultaneously sendCOD, ammonia-nitrogen, heavy metals, and multiple online monitors provide uninterrupted mixed water samples.

Manual sampling port: Equipped with a manual sampling port, capable of performing manual comparison of mixed water samples.

Record: Each record should include the sample bottle number, sampling time, sample quantity, sampling method, storage mode, number of times sampled, and parallel sample number.COD value, NH3-N value, total phosphorus value, and total nitrogen value, capable of recording up to 10,000 data records.

Power Failure Protection: Automatic protection during power failure; parameters are not lost upon power interruption, and the instrument can automatically resume its original operating state after power is restored.

Remote Control(Optionally): Allows for remote reset, remote start of sampling, remote parameter modification, remote retrieval of sample records, and can proactively upload sample records. Additionally, custom communication protocols for users can be provided.

Digital Temperature Control: Refrigerator with digital temperature control and uniform heating system for precise and even temperature distribution.

Automatic Rinse: Rinse the pipeline and sampling bucket with the water sample to be tested prior to each collection, ensuring the representativeness of the retained sample.

Automated Mixing Drum Emptying: The mixing drum features a quick automatic emptying function.

External Pump Control: Directly control the external pump to extend the sampling distance.

Additive Function for Preservative (optional): Automatically add preservative as per customer requirements.

Pipe Optimization: Sampling pipeline for supply samples is made of rigid materialPVC materials, ensuring the effectiveness and timeliness of water sample collection.
