The LM80 is a high performance laser transmitter that accurately measures level, distance and position over long ranges in extreme environments. It is a non-contact, level measuring instrument designed for granular solid materials and opaque liquids.

Based on pulsed laser technology, the LM80 embodies speed and accuracy in a single, easy to use and install product. Whether measuring a few meters into the confined space of a crusher, or to the bottom of the tallest silo, the LM80 with its laser pointer and long range is the plug-and-play solution to level measurement.
The LM80 features advanced timing and sophisticated signal processing for pinpoint accuracy at up to 100 m (330 ft.) for level applications and up to 150 m (500 ft.) for positioning applications.
