The NanoCount 65C is one of the smallest 65 nm liquid particle counters on the market designed to monitor ultrapure process chemicals. Based on state-of-the-art technology and built by Lighthouse, they are 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.

Incorporating the latest in laser optical particle counting technology and designed for reliability, the NanoCount 65C is intended for continuous trouble-free operation.
