Vacuum Gauges

275i 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:

Low-cost, plug-compatible, direct drop-in replacement for the most basic Granville-Phillips Mini-Convectron models
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
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
Controllers feature universal power and are CE marked
