Mixed Supply Sample Self-Draining Water Quality Automatic Sampler (DR-803N)

      The water quality automatic sampler is widely used at pollution sources, wastewater treatment plant inlets and outlets, and is used in conjunction with online monitors 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, enabling continuous sampling and ensuring that the collected water samples are more representative. It features AB barrel mixed sample supply, automatic emptying of reserve bottles, and automatic addition of preservatives to stored water samples. It is an ideal complementary equipment for online monitoring systems of water pollution sources and a comprehensive solution for total emissions reduction.

　　Feature Highlights

Sampling Function: Offers various triggering methods, including timed sampling, proportional to time, proportional to flow, flow tracking, external control sampling, and serial port control.

Sample Retention Function: Allows for exceeding standard sample retention, simultaneous sample retention, direct sample retention, and serial port controlled sample retention.

Sample Supply Function: Capable of providing continuous mixed water samples to multiple online monitors such as COD, ammonia nitrogen, and heavy metals; Manual Comparison Sampling Port: Equipped with a manual sampling port, enabling manual comparison of mixed water samples.

Record: Sample retention records, door opening/closing records, power outage records, and alarm records.

Power Failure Protection: Automatic protection during power outage, automatic restoration to operation upon power-on.

Digital Temperature Control: Refrigerated container with digital temperature control and uniform heating system for accurate and even temperature distribution.

Automatic Rinse: Rinse the pipeline with the water sample to be tested before each sampling to ensure the representativeness of the retained sample.
