The automatic water quality sampler, featuring embedded control technology, is a fully functional portable device. It supports multiple sampling triggers including time-based proportional sampling, scheduled sampling, cyclic sampling by date, rainfall-triggered sampling, and over-limit sampling. The system can be connected to flow meters, pH meters, and rain gauges for online operation, automatically initiating sampling based on preset threshold values.
The automatic water quality sampler also has password protection, power failure protection and other protection functions, refrigeration function, can be used in sewage well, natural river, outdoor sampling and other occasions.

Main Functions
Sampling triggers: Time-based proportional sampling, scheduled sampling, cyclic date sampling, flow proportional sampling, liquid level proportional sampling, instantaneous sampling, rainfall-triggered sampling, and exceedance sampling (pH).
Sampling methods: Single sampling, mixed sampling, and parallel sampling.
Sampling records: Automatically store sampling record information, including sampling time, triggering method, sampling quantity, sampling method, sampling frequency, sampling success/failure, pH value and temperature value at the time of connection. All records support page-by-page and quick view. The records can be exported to SCV locally.
Alarm recording function: Automatically stores sample failure, abnormal allocation arm, and other recording information, including alarm time and alarm information.
Rainfall records: Automatically record the time and amount of rainfall, as well as the intensity of rainfall in 1h and 24h.
Flow record: When connected to a flow meter, the current value can be displayed in real time. Instantaneous and cumulative flow can be automatically recorded at preset time intervals. The flow record can be exported locally as SCV.
PH logging: Displays real-time current values and automatically records pH and temperature data at preset intervals. The recorded data can be exported locally as SCV files.
System logs: contain calibration records for water samples, pH calibration records, and modification records of sampling modes and parameters. These records can be exported locally as SCV files.
Battery level: The sampler is powered by a battery, and the screen displays the current battery level as a percentage.
Water sample refrigeration function: the sampler can deploy a refrigerant module inside to refrigerate the water sample.
Automatic pipeline cleaning: The pipeline of water sample to be collected is automatically cleaned before each sampling to prevent water sample contamination. The cleaning time can be set.
Automatic pipeline drainage: Automatically drain water in the pipeline before and after sampling to prevent sedimentation and blockage. The drainage time can be set. The sampling head is equipped with a filter screen or filter bag to reduce blockage.
Measurement calibration function: The sampling time, flushing time, draining time and corresponding sampling amount of the sampling pipeline can be set.
Anti-overflow function: The system controls the total sampling amount not to be greater than the sampling bottle capacity, and stops sampling when the sampling bottle is full to prevent water sample overflow.
Password function: The system login password can be set to
Doppler flowmeter configuration: Supports cross-sectional parameter configuration and height correction for the Doppler flowmeter.
Communication interface: Features an external communication interface, with RS485 as the default type.
Analog input interface: Equipped with 2-channel (4-20) mA analog input for connecting flow meters and level meters.
System upgrade: Supports TF card for system upgrade and data export.
Power supply: 24V lithium battery, charged by AC 220V/50Hz mains.
