DR-803F2 Automatic Water Quality Sampler (Bottom Self-Draining Type)

This water quality automatic sampler is a new generation intelligent model developed by our company. The sampler can perform timed sampling, proportional sampling by time, proportional sampling by flow rate, and retains samples exceeding standards.Automated sampling; in situations where the sampler is unattended for extended periods, it can automatically drain expired water samples and proceed with the next collection, ensuring continuous operational capability. Suitable for environmental protection departments, wastewater treatment plants, drainage management authorities, and wastewater discharge enterprises for the automated collection, refrigeration, and drainage of water samples from surface water, water treatment processes, and corporate main effluent outlets.

Bottle Sampling Mode: Instrument capable of1 to 25 bottles for sampling, with the number of bottles freely adjustable.

Multiple sampling modes: timed, proportional by time, proportional by flow, flow tracking, and sample retention for exceeding limits.

Automatic Drainage Function: The instrument can automatically drain water samples, when no sampling has been performed for an extended period.The instrument can automatically empty the water sample from the sampling bottle, perform the next sampling, ensuring the instrument remains in continuous operational status.

Sample Record Feature: Allows recording of each sampling's time, quantity, and sample bottle number.Sample mode and other information,Storeable1,000 sample records

Operation Record: Records the opening time of the water sample cooler door and the change time of important parameters each time.

Communication Function: AccessibleCommunicate with other instruments via RS-232/Rs-485.

External Interface: Capable of connecting flow meter signals and level sensor signals4mA～20mA；

External pump control function: When the sampling distance exceeds the range of the built-in sampling pump, an external sampling pump can be used for relay sampling.

 Power failure protection function: Upon power restoration after a sudden outage, the instrument can automatically resume its original operating state, and the instrument parameters will not be lost after the power failure.

Sample Constant Temperature Storage Function: Achieves constant temperature storage of samples under the control of the temperature control system.4°C ± 2°C environment。
