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).

The MKS 937B Digital Combination Vacuum Gauge Controller operates up to six vacuum pressure sensors simultaneously. This highly flexible vacuum gauge controller supports a wide range of sensor technologies, including cold cathode, hot cathode, standard Pirani, convection Pirani, Baratron® capacitance manometers and absolute Piezo sensors for a measurement range from ultra-high vacuum to above atmospheric pressure. The 937B controller is designed for versatility, reliability and economy. The large, easy to read, liquid crystal display provides readout for up to six sensors simultaneously. The back lit LCD display, intuitive menus and simple push button front panel, allows for ease in setup of the 937B. This controller enables the use of any sensor card in each of the sensor card slots. The 937B can be configured with up to three hot or cold cathode type gauges, or three dual sensor cards for a maximum of six gauge connections.

The MKS vacuum gauge signal cable connects 937B controllers to GP275 vacuum gauges. It connects to the back of the MKS controllers and to the side of the GP275 vacuum gauges. This is the Cable ONLY.
