[Description]

The 270 ionization gauge controller is a precIsion instrument designed to indicate vacuum pressures from I Torr to 10 -8 Torr, I mbar to 10-8 mbar, or 100 Pasca I to 10-6 Pascal, air equivalent. The basic unit is comprised of a power supply, electrometer, emission controller, and ion gauge meter. Dual thermocouple gauge capability and process controls on the ion gauge and thermocouple gauges are included on some models. Recorder outputs provide capability for remote indication as well as continuous monitoring. In the basic controller the 270 will display pressure data in five linear decades, 10-4 to 10 -8 Torr. The range of readable data is from 0.3 x 10-8 to 12 x 10 -4 Torr. The controller is designed to utilize a Bayard-Alpert type transducer with sensitivity ranging from 10/Torr to 25/Torr. The unit is shipped pre-adjusted for directly indicating pressure of a gauge having a sensitivity of 10/Torr, corresponding to an emission current of 2 mAdc.
