275 convectron convection-enhanced pirani vacuum sensor

Overview

The Granville-Phillips® 275 Convectron® Pirani Vacuum Gauges have been the world-standard convection-enhanced Pirani gauge for over 35 years and are used in thousands of vacuum processes to accurately measure pressure from atmosphere to 10^-4 Torr. To assure the highest level of accuracy and gauge-to-gauge reproducibility, every Convectron gauge is individually calibrated at the factory, thereby making controller adjustment unnecessary.

Wide vacuum pressure measurement range from atmosphere to 1x10^-4 Torr
Individually calibrated gauges assure the highest measurement performance
Easy installation in space-restricted locations
Temperature compensation offsets the effects of ambient temperature changes
Wide selection of vacuum fittings simplifies installation on your vacuum system
