Don't be fooled by sizing tricks, false count subtractions, or marketing gimmicks. When using in-situ particle counters for your UPW applications you want the most sensitive detection at the minimum particle size. The Nanocount line of UPW Liquid Particle Counters have the lowest false count rate, and are focused on true sensitivity. Let us show you what you have been missing.

NanoCount 50C and NanoCount 65C are two of the smallest 50nm and 65nm 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 50C and 65C have integrated manual flow control, built in leak detector and 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 50C and 65C to connect to standard corporate Ethernet LANs as easily as it connects to Facility Monitoring Systems. The compact size of the NanoCount 50C and 65C allow them 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 50C and 65C are intended for continuous trouble-free operation.
