The 370501-B1A-T1 Stabil-Ion® Vacuum Gauge Controller features Torr units, a 120 VAC power cord for North America and Japan, and a 19 inch rack mount for the controller and power supply. An RS-485 interface allows easy integration with computer controlled systems. A Dual Convectron Gauge card is included in Slot Y. Two process control set point relays are available to control other vacuum equipment such as valves, pumps, timers, and safety interlocks. Settings are adjustable and are stored in nonvolatile memory. Stabil-Ion® vacuum gauge controllers combine the latest technology in ionization gauges and control electronics, giving you the most reliable and accurate vacuum pressure measurements for your systems and research. Bright LEDs display the pressures read by the Stabil-Ion and Convectron Gauges. Other features include analog output, selectable emission current, degas timer, and selectable N2 /Ar gas for Convectron gauge. If the Stabil-Ion Gauge and memory module are replaced, processing results are much more likely to remain the same. If you need vacuum measurements that are accurate and repeatable over time, the Stabil-Ion Gauge and Controller is your answer. Every Stabil-Ion Gauge is individually calibrated at 15 pressure values and supplied with a memory module matched to its own calibration data. This provides gauge-to-gauge reproducibility which is essential for process replication.
