The MKS, Granville-Phillips® 275 Convectron® Pirani Vacuum Gauge, provides exceptionally reliable performance for low vacuum measurement.
The 275 Convectron® Pirani Vacuum Gauge provides reliable measurement from 10-4 Torr (10-2 Pascal) to Atmosphere. Its high accuracy and repeatability help to ensure that processes start at the desired pressure - time after time.
The 275 Convectron® Pirani Vacuum Gauge delivers fast response time - in milliseconds - compared to thermocouple-type gauges that respond in seconds.
- Wide range vacuum pressure measurement from atmosphere to 1x10-4 Torr
- Individually calibrated gauges assure the highest measurement performance
- Easy installation in space-restricted locations
- Wide selection of vacuum fittings simplifies installation on your vacuum system
- For use with several of MKS, Granville-Phillips Division’s vacuum gauge controllers
- Temperature compensation offsets the effects of ambient temperature changes
- Rugged construction
