The 358501-B1A-M1 Granville-Phillips® Micro-Ion® Vacuum Gauge Controller is designed to obtain the highest performance from Granville-Phillips® Micro-Ion® Gauges. It is capable of measuring from a lower limit in the 10-10 mbar range to 7x10-2 mbar. Pressure measurements are extended to Atmosphere with the Dual Convectron® Vacuum Gauge card. This reliable vacuum gauge controller is compact and easy to use. The extruded aluminum, half-rack design fits easily into your control rack. Infrequently used controls are located behind the front panel door to provide an uncluttered appearance. Large, bright green, flicker-free LED digital displays make measurements easy to read - even from a distance. Two setpoint relays can be used to control a variety of system functions such as switching valves, setting interlocks, and setting alarms. Integration into computer-controlled systems is also possible through the use of the RS-485/422 interface. It includes 120V power plug for use in North America or Japan.
