LSPEC 720 Automatic Water Quality Sampler
Product Description
Simultaneously, the sampler is equipped with comprehensive sample retention functions, supporting multiple retention modes such as automatic retention of water samples exceeding standards, remote command retention, external switch signal control retention, continuous retention, and communication-triggered retention. It can accurately capture water samples from critical periods and abnormal water quality, providing reliable and effective sample evidence for tracing the source of water quality exceedances and analyzing pollution events.
In terms of data and control, the sampler seamlessly integrates with various online water quality analysis instruments and environmental monitoring management platforms via a standard communication interface, supporting remote real-time monitoring, status query, parameter configuration, and command issuance, truly achieving remote management of the entire sampling process.
The entire unit features a high degree of automation, informatization, and intelligence, significantly reducing manual on-site operation, improving sampling efficiency and data reliability. It is widely applicable to scenarios such as rivers, lakes, drinking water sources, municipal water supply and drainage networks, industrial parks, and enterprise sewage outlets, providing stable and efficient sampling support for online water environment monitoring, pollution early warning, and environmental supervision.
