Granville Phillips 270 Ion Gauge Controller With Dual TC, and Autorange for High Vacuum Measurement
This Granville Phillips (Model 270) ion gauge controller is a precision instrument designed to indicate high vacuum pressures from 1 to 1x10-8 Torr and has dual thermocouple gauges and autoranging. This model does not support process control. The two independent thermocouple gauges allow for pressure measurement in the range of 0.001 to 1 Torr while the ion gauge allows for pressure measurement in the 9x10-4 to 1x10-8 Torr range. The basic unit is comprised of a power supply, electrometer, emission controller and ion gauge meter. These Granville Phillips 270 high vacuum ion gauge controllers operate on either 115 or 220 VAC. Ion gauge cable and ion gauge tubes are available but sold separately.
