Description

Lesker 275 Convection Sensor | 1/8″ NPT or KF25 | Convection Enhanced Pirani Gauges

Lesker – These KJLC 275 convection sensors offer excellent accuracy, repeatability and value for a wide range sensor (0.1 mT to 1000 mbar/Torr).  These gauge tubes and controllers are low-cost drop-in replacements to the Convectron® brand of MKS / Granville-Phillips® 275 gauges (MKS MODELS: 275071; 275203).

Overview LESKER MODELS: KJL275071; KJL275196

• Gauge, Convectron Equivalent
• 10E-4 (0.1 mT) to 1000 Torr
• 1/8″ NPT or KF25 (depending on selection)
• Only convection enhanced pirani gauge with native KF25 interface
• Interconnect cable available as add-on (KJL375 or MKS to Convectron Tube, 10′ long)

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
• The convection enhanced pirani gauges work with the DigiVac StrataVac Controller and can be calibrated with the controller for optimal accuracy. NIST certified calibration is also available.
• Ideal if you need a replacement gauge for GP 275, 375, and 475 convection gauge controllers or other compatible controllers
• Note: 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.
