Portable discrete water sampler for monitoring wastewater WS-9350
This water quality automatic sampler adopts embedded control technology and is a fully functional vehicle-mounted sampler. It is suitable for sampling in multiple scenarios such as surface water and pollution sources, and can achieve schedule based sampling, time proportional sampling, flow proportional sampling, level proportional sampling, rainfall sampling.
(Flow meters, level gauges and rain gauges need to be purchased separately by the user.)

Main Functions
Multiple sampling modes: Time-proportional sampling, date-cycle sampling, flow-proportional sampling, level-proportional sampling, timed sampling, immediate sampling, and rain gauge-triggered sampling, with support for setting the day of the week.
Multiple sampling methods: Single-shot sampling per bottle, multiple-shot sampling per bottle, and sampling multiple bottles at once.
Water sample refrigeration: Equipped with a refrigerator for refrigerated storage of water samples.
Heating: Both the refrigerator and the sampling pump area are equipped with heating modules to ensure normal operation in low-temperature environments.
Temperature control: Displays the refrigerator temperature in real time in digital form, with adjustable upper and lower temperature limits.
Automatic pipe rinsing: Use the pre-sampled sampler to rinse the pipe before sampling. Automatically rinses the pipes with water samples to prevent contamination, with a programmable number of rinse cycles.
Automatic Pipeline Drain: Automatically drains water from the pipes before and after sampling to prevent sedimentation and clogging. The drain time is programmable, and the sampling head includes a filter or bag to reduce clogging.
Calibration: Programmable drain, rinse, and sampling times, as well as the corresponding sample volume.
Password: A system login password is available, which can be set to prevent program modification. The password can be disabled.
Multiple Power Supply Options: Supports three power supply options: AC 110V/AC 220V (50/60Hz) +/-10% plug, DC 12V tinned (polarity marked) power cord, and car cigarette lighter plug (DC 12V).
