Vacuum Gauges

375 Series Panel Mount / Benchtop Gauge Controller

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 lets you monitor your vacuum system from 10^-4 to 1,000 Torr (10^-4 to 1,333 mbar) with a single gauge
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
Includes two set points, user-selectable analog output, and RS-232/485 interfaces
Analog output is configurable as a non-linear S-curve, log-linear, or user-scalable linear
Space-saving 1/8 DIN panel mount housing which can also be used as a benchtop unit
Powered by universal 100–240 VAC or 12–30 VDC
Controllers feature universal power and are CE marked
