Featured Applications
- Urban sewage treatment plant: Sampling and retention of samples at various points in the plant area to monitor the effectiveness of sewage treatment
- Industrial discharge outlet: Sampling of enterprise discharge outlet to achieve automatic retention and evidence collection for exceeding standards
- Industrial park: Centralized sampling of wastewater in the park, conducting water quality risk assessment
- Surface water environment: Sampling of rivers, lakes, and reservoirs, conducting water quality monitoring and evaluation
- Municipal pipeline pumping station: sampling of pipeline outlet, investigation of illegal and leaking discharge problems

Main Function Introduction
- Diversified sampling: Select timing, flow, proportion, quantitative and other modes as needed to meet routine monitoring requirements.
- Excessive retention of samples: Linked with online analyzers, the water sample is automatically retained for traceability verification after triggering the excessive signal.
- Sample preservation: Low temperature refrigeration (4 ± 2 ℃), supporting automatic addition of preservatives.
- Data management: Automatically records sampling time, bottle number, and sampling volume, data is not lost when power is off, and supports query and export.
- Remote control: Implement remote start stop, parameter setting, and status uploading through communication interfaces.
- Security protection: multi-level login permissions, access control, fault sound and light/voice alarms.
