The DR-803Q Water Quality Automatic Sampler is a research outcome of the DR-803 series water quality automatic samplers, independently developed and produced by our company.

The water quality automatic sampler is widely used at pollution sources and at the inlets and outlets of wastewater treatment plants.COD, ammonia nitrogen, heavy metals, and other online monitoring instruments are being used in conjunction.

The water quality automatic sampler utilizes a twist-off glass bottle as the sampling container, offering excellent sealing properties, and the sampling bottle can be directly taken away.The sampling bottles feature tilting for emptying; they are cleaned using high-pressure pure water, ensuring excellent cleaning results and can be reused multiple times. They are under centralized control, seamlessly integrated with various online monitoring instruments, achieving functions such as retained samples for exceeding standards, external control retained samples, and simultaneous retained samples. Particularly suitable for automatic water quality monitoring stations at river cross-sections and drinking water sources, they are a component of the surface water quality automatic monitoring system.
