WebCold cathode measurement technology has evolved significantly from the first Penning ionization gauges. These modern gauges provide accurate, repeatable, and reliable measurement results. Double inverted magnetrons reliably measure a wider vacuum range than most Bayard-Alpert gauges and are not fraught with X-ray or ESD errors. WebCRTC stands for "Cathode Ray Tube Controller" but wikipedia prefers "Video Display Controller". They are still often called CRTCs - technical terms can be slow to change sometimes. There is always a more complicated explanation, but an adequate summary is that each CRTC corresponds to a video buffer on a video card that is destined to be output.
