KJLC® 275 Series Gauge Tubes

These gauge tubes and controllers are ideal for new applications or as low-cost drop-in replacements to the Convectron^® brand of MKS / 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
• Rugged design withstands more abuse and harsh environments
• Significant savings—no changes to your system, you use your existing competitor's controllers or cables
• 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. Note that this request must be made upon order of the unit.
• Interconnect cable 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.

A Complete Package Consists of
