MKS, Granville-Phillips® Vacuum Gauges & Sensors cover a broad spectrum of vacuum measurement solutions, including:

• Stabil-Ion® Vacuum Gauges are all-metal Bayard-Alpert (B-A) style gauges developed to maintain long-term accuracy over the life of the product.
• Micro-Ion® Vacuum Gauges are the world's smallest Bayard-Alpert (B-A) style gauge in an all-metal enclosure.
• Convectron® Vacuum Gauges have been the world-standard convection-enhanced pirani gauge for over 3 decades and are used in thousands of vacuum processes to accurately measure pressure from 10^-4 Torr to Atmosphere.
• Classic Granville-Phillips® glass and nude Bayard-Alpert (B-A) hot cathode ionization vacuum gauges provide good vacuum measurement at an economical cost.
• 431 & 423 I-Mag® Cold Cathode gauges provide long lifetime over a wide measurement range

(10^-4 Torr to Atmosphere)

Convection-enhanced Pirani pressure/vacuum gauges

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.
