Incorporating the latest in laser optical particle counting technology, Lighthouse designed the REMOTE LPC 0.5μm liquid particle counter for continuous trouble-free operation.


     With a sensitivity of 0.5μm at a flow rate of 100 ml per minute, the REMOTE LPC 0.5μm provides real-time continuous data collection at a cost-effective price per point.


     These compact liquid particle counters provide versatile mounting options and can be installed where space is at a premium.


     The REMOTE LPC 0.5μm integrates seamlessly into large facility monitoring and management systems and transfers up to 2 channels of simultaneous particle count data using the LWS 4-20mA protocol.


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