The Liquid Grab Sampler (LGS) adds value to the Lighthouse Remote Liquid Particle Counter by providing a reliable pump system and NEMA enclosure to help integrate it with process equipment and large facility monitoring systems.

The LGS was designed to provide reliable sampling in a variety of applications such as parts washing, waste water monitoring and process monitoring for many different environments.

It incorporates a state-of-the-art pump, precision pump speed control, precision fl ow meter and externally controlled low voltage pump switching. The LGS is easy to configure, operate and monitor. The Remote Liquid Particle Counter (sold separately) provides particle count data in real time. All data can be transferred to a single computer or a facility monitoring system.
