The Stanford Research Systems IGC100 Ion Gauge Controller measures and controls high vacuum pressures across an exceptionally wide range: 1000 Torr down to ultra-high vacuum (<10⁻¹¹ Torr). This precision instrument integrates with Bayard-Alpert ionization gauges, convection-enhanced Pirani gauges, and capacitance manometers, delivering stable readings with up to 15% reduction in measurement uncertainty compared to traditional controllers.
The 4.7-inch touchscreen LCD (320 × 240 pixels) displays pressure data in multiple formats: numeric readings, bar graphs, and pressure versus time curves. The display updates twice per second and supports Torr, mbar, bar, Pa, or micron units. A real-time clock provides precise timestamps for continuous data logging of pressure, ADC voltages, and relay activity, enabling detailed pump-down cycle monitoring and vacuum system performance tracking.
