The NanoCount 65C+ is one of the smallest 65 nanometer liquid particle counters on the market designed to monitor ultra pure process chemicals. It 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 65C+ provides industry standard RS-485 Modbus and 4-20 mA 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 65C+ to connect to standard corporate Ethernet LANs as easily as it connects to Facility Monitoring Systems.

The compact size of the NanoCount 65C+ allows it to be installed where other liquid particle counters won't fit, including point-of-use process control applications.
