The new series of remote vacuum gauges are designed for stand-alone vacuum measurement and control. The 7ER/FR gauges measure in the range of 10-2 to 10-11 torr and use patented 7E/F double-inverted magnetrons, which provide high and ultra high vacuum measurement. The 2AR gauges use the 2A Sensor, which measures in the range of 1 to 20,000 Km. The sensors can be changed in seconds and operates from low voltage dc. The 4AR gauges measure in the 10+3 to 10-3 torr range with the patented 4A Sensor, which can be changed in less than one minute.
