MKS Granville-Phillips® 358 Micro-Ion® Vacuum Gauge Controller, Dual Convectron Card, Torr, 115 VAC, 1/2 Rack. MKS Granville-Phillips® Part Number: 358501-010-T1. This MKS Granville-Phillips® half-rack, model 358 Micro-Ion® high vacuum gauge controller is set up to operate a Micro-Ion® gauge and a single convectron gauge. This 358 Micro-Ion® Controller is capable of measuring from a lower limit in the 10-10 range to 5x10-2 torr. Pressure measurements are extended to Atmosphere with the Dual Convectron® Vacuum Gauge card. Additional convectron control cards can be ordered to operate an additional convectron sensor. This 358 controller configuration is made to run on 115 VAC. Pressure readout is via three front panel displays, analog output, and available computer interface. The Micro-Ion® gauge measures ultra high vacuum pressure from 5x10-2 to 10-10 torr while convectron sensors are typically used to measure roughing line vacuum pressure from atmosphere to 10-4 torr. Cables and ion gauge tubes are available and sold separately.

MKS Granville Phillips Part Number: 355001-TA 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. These gauges have cooler operation, at only 8% of the power consumption of a traditional glass or nude gauge, the Micro-Ion Gauge generates significantly less heat-related process or experiment disturbances. Port shield protects the electrode assembly from damage during assembly or vacuum chamber maintenance, and provides a stable electrical environment for improved measurement performance. They have all-metal enclosures which prevents grid and filament damage during mounting and eliminates the risk of glass breakage.

MKS Granville Phillips 275 Convectron Gauge Vacuum Pressure Measurement Sensor, 1/8 Male NPT MKS Granville Phillips Part Number 275071 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 1x10-4 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).

MKS Granville Phillips 275 Convectron Gauge Vacuum Pressure Measurement Sensor, Conflat 2.75 inch MKS Granville Phillips Part Number: 275238 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 1x10-4 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.
