The DR-803K Water Quality Automatic Sampler is a specialized sampler designed and manufactured by Derun Hou Tian for online monitoring systems of water pollution sources, specifically for mixed sample supply and over-standard sample retention. It is widely used at the inlets and outlets of pollution sources and wastewater treatment plants, and is used in conjunction with online monitors for parameters such as COD, ammonia nitrogen, total phosphorus, total nitrogen, and heavy metals. It features a flow tracking sampling mode that can automatically adjust the sampling flow based on instantaneous flow, enabling continuous sampling and ensuring that the collected water samples are more representative. It has features A, BBucket mixing sample function, capable of being connected to an online monitorSupply uninterrupted mixed water samples.

The water quality automatic sampler can continuously supply mixed water samples to the on-line monitor, achieving the functions of collecting mixed water samples, mixing them, temporarily storing them, retaining samples that exceed the standard, and triggering alarms.Storage of samples, automatic cleaning and emptying of mixing tanks, and sample protection features, in compliance with HJ353-2019, HJ354-2019, HJ355-2019, HJ356-2019For countries with environmental standardsProtecting standards requirements, this is an ideal配套device for a comprehensive on-line water pollution source monitoring system solution.

Sampling Function: Offers various triggering methods for sampling, including timed sampling, proportional to time and flow, flow tracking, externally controlled sampling, and remote start.

Sample Retention Function: Enables over-limit sample retention, synchronized sample retention, direct sample retention, and serial port controlled sample retention features.

Sample Supply Function: Capable of supplying samples simultaneously toCOD, ammonia nitrogen, heavy metals, and multiple online monitors provide continuous mixing of water samples.

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

Record: Record each sample bottle number, sample time, sample quantity, sampling mode, sample mode, number of samples, parallel sample number.COD value, NH3-N value, total phosphorus value, and total nitrogen value; capable of recording up to 10,000 new data records.

Power Failure Protection: Automatic protection upon power failure; parameters will not be lost after power failure, and the instrument can automatically resume its original working state upon power restoration.

Digital Temperature Control: Refrigerator accurately controls the temperature, with an even heating system installed, ensuring uniform and precise 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 automated emptying function.

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

Pipe Optimization: Sample collection pipeline for rigid pipingPVC material, ensuring the validity and timeliness of water sample collection
