The REMOTE 5104PN meets the stringent requirements of today’s aseptic processing applications. Incorporating the latest laser optical particle counting technology, Lighthouse designed the REMOTE 5104PN for continuous trouble-free operation.


     The REMOTE 5104PN uses a built-in vacuum pump and flow control system to insure accurate and reliable sensor performance.


     With a sensitivity of 0.5 micron at a controlled flow rate of 1.0 CFM, the REMOTE 5104PN provides continuous real-time data at a cost-effective price per point.


     The REMOTE 5104PN integrates seamlessly into large facility monitoring and management systems and transfers up to 4 channels of simultaneous particle count data using RS-485 MODBUS or Ethernet MODBUS TCP.


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