The NanoCount 50+ is the smallest 50 nanometer liquid particle counter on the market and incorporates a 3-1/2 inch TFT Touch Screen to simplify the user interface. Based on state-of-the-art technology and built by Lighthouse, it is backed by a two-year warranty and international support.


     The NanoCount 50+ provides industry standard RS-485 MODBUS and 4-20mA communication protocols so integration into facility monitoring systems or use as a stand-alone device is quick and easy.


     Using its integrated Ethernet TCP/IP interface allows the NanoCount 50+ to connect to standard corporate Ethernet LANs as easily as it connects to Facility Monitoring Systems.


     The compact size of the NanoCount 50+ allows it to be installed where other liquid particle counters won’t fit, including point-of-use process control applications.


     Incorporating the latest in laser optical particle counting technology and designed for reliability, the NanoCount 50+ is intended for continuous trouble-free operation.
