KJLC® Convection Enhanced Pirani Gauges


These gauge tubes and controllers are ideal for new applications or as low-cost drop-in replacements to the Convectron® brand of Granville-Phillips® gauges.

Features

  • New applications or low-cost drop-in replacements for Convectron gauges, Mini-Convectron® modules, and controllers
  • Less prone to damage from mechanical shock or vibration than competitor's tubes
  • Less outgassing and faster response to pressure changes than competitor's tubes
  • Wide measuring range from 1 x 10-4 to 1,000 Torr(1.3 x 10-4 to 1,333 mbar)
  • Controllers feature universal power and are CE marked
