KJLC® 300 Series Gauge with Integrated Controller & Display

The 300 series vacuum gauge modules are ideal for new applications or as low-cost drop-in replacements to the Mini-Convectron® brand of Granville-Phillips® gauges.

Features

  • Wide measuring range: 10-4 Torr to 1,000 Torr (10-4 to 1,333 mbar)
  • Performance identical to existing competitor's gauges
  • 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
  • New applications or low-cost, plug-compatible, drop-in replacement module for Granville-Phillips® Mini-Convectron®
  • Performance identical to existing competitor's mini-convection modules
  • Rugged design withstands more abuse and harsh environments
  • No changes to your process—a single vacuum gauge can monitor your vacuum system pumpdown and venting; helps keep your process up and running, even if it's not a laboratory environment
  • CE marked, RoHS compliant
  • NIST traceable calibration certificates available upon request.
  • Power supply sold separately.
  • Gauges are calibrated for direct readout of nitrogen or air. Do not attempt to use with other gases unless accurate conversion data for N2 to the other gas is properly used.
