The NanoCount 25 are the world's first nanometer liquid particle counters. Based on our new state-of-the-art technology and built by Lighthouse, they are backed by a one year warranty and international support.

The NanoCount 25 include built-in color displays Modbus communication protocol. Integration into facility monitoring systems or use as a stand-alone device is quick and easy.

By incorporating Solid-State laser particle counting technology and designing for reliability, the NanoCount 25 are intended for continuous trouble-free operation.
