Description
LSS is a universal device for monitoring the liquide level of your chromatographic system. The daily task in the chromatographic laboratory is the manipulation of mobil phases. The operator must check the supply of solvents at the inlet of the device and regular monitor the condition of the waste solvent container. The LSS-205 greatly simplifies these tasks.
LSS-205 is a universal accessory for any (chromatographic) system. The level sensors used in the LSS-205 system are contactless, do not require immersion in liquid, and are installed on the outer shell of a non-metallic solvent container. The method of mounting the sensor allows placement on a container of virtually any shape and size.
The LSS-205 central unit is ready to process the signal from up to five liquid sensors, which can be individually set to trigger an alarm in the event of a missing or present liquid. The error status of the individual sensors is indicated optically directly on the central unit and the alarm can be accompanied by an acoustic signal.
External optical signaling (green/red) and a loud siren suitable for a noisy environment are available as an option to the central unit.
