The World’s Smallest Ionization Gauge. The Micro-Ion Gauges occupy less than 10% of the volume of conventional glass gauge or nude gauges, allowing easy installation in complex, tightly packed vacuum systems. With high performance patented dual ion collector design increasing electron path length and ion collection efficiency providing high performance in a small volume. Having long term stability, the grid windings are attached to the grid posts every 180° for greater sensitivity and stability. The dual filaments helps provide long gauge life. Unscheduled downtime is avoided by using the second filament as a back-up until the gauge can be replaced during regular maintenance procedures.

The 275 MKS Granville Phillips convectron pressure measurement gauge tube sensor is the industry standard convection-enhanced Pirani gauge. The MKS Granville Phillips 275 measures vacuum pressure from atmosphere to 1x10 Torr and are ideal for roughing and foreline pressure measurement. It provides reliable fast response measurement, in milliseconds rather than seconds as in the case with thermocouple-type gauges. The high accuracy of the MKS Granville Phillips 275 Convectron vacuum gauge sensor and repeatablilty help insure that processes start at the desired pressure time-after-time. However, they are sensitive to the chemical composition of the gases being measured and are termed a relative pressure measurement method, that is, they determine the pressure indirectly from the thermal conductivity property of the gas medium. (MKS Granville Phillips 375 Convectron Controller shown in photographs is avaliable but not included at list price).
