The NanoCount 30+ is the world's first 30 nanometer liquid particle counter. Based on out new state-of-the-art technology and built by lighthouse, it is backed by international support


     The NanoCount 30+ includes abuilt-in color display for viewing real time data and uses the industry standard 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 30+ is intended for continuous trouble-free operation.



Designed and built by Lighthouse – a name you can trust.

Lighthouse is an ISO 9001:2008 Registered Company.
