Flow System
The Jerome
®
431-X's flow system is the crucial link between the sensor and the sample. For the
instrument to perform correctly, the flow system must be properly maintained. The user
maintainable components of this system are the intake filter (.25 inch fritware), a C/M Filter, two
scrubber filters and connecting tubing.
Check the Preventive Maintenance Calendar on page 18, for a suggested schedule for changing
fritware and scrubber filters. The Tygon™ tubing in the system must be free of crimps for
proper flow.
