KJLC® 392 Series Wide-Range Combination Gauges

The KJLC 392 is our KJLC 354 ionization gauge module with the ability to control and display two convection gauges.

Features

  • Full measurement range from atmosphere down to 1 x 10-9 Torr (1.3 x 10-9 mbar)
  • Built in controller and display eliminates the need for expensive external controllers and cabling
  • Dual Hot Filament design, rugged and compact metal construction
  • A drop-in plug-and-play replacement for the Granville Phillips® Micro-Ion® module
  • Field servicable - the sensor assembly can be easily replaced
  • CE Marked, RoHS compliant
