KJLC® 275i Series Gauge with Integrated Controller & Display

The 275i 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:

  • 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
  • Built-in digital display
  • Wide measurement range: 10-4 to 1,000 Torr (10-4 to 1,333 mbar)
  • Wider measuring range and better accuracy than traditional thermocouple gauges
  • 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.
