Vacuum Gauges

300 Series Gauge with Integrated Controller & Display

These gauge tubes and controllers are ideal for new applications or as direct "drop-in", low-cost equivalents to the 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 Convectron gauges
Less prone to damage from mechanical shock or vibration than Convectron tubes
Less outgassing and faster response to pressure changes than Convectron tubes
New applications or low-cost, plug-compatible, drop-in replacement gauge for Convectron gauges and Mini-Convectron modules
Performance identical to existing Convectron gauges
Rugged design withstands more abuse and harsh environments
Significant savings—no changes to your system, you use your existing Convectron controllers, cables, and modules
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
Controllers feature universal power and are CE marked
