These reconditioned MKS HPS Series 943 Cold Cathode vacuum gauge controllers are compatible with the Series 423 I-Mag sensor for OEM or industrial use and the 421 sensor for UHV use. The Series 943 Cold Cathode vacuum gauge controller is designed to be user-friendly and to provide fast, reliable pressure measurement from 10-10 to 10-2 Torr. The 943 Cold Cathode Vacuum Gauge is well-suited for industrial, process and analytical applications including pressure measurement of high vacuum chambers and control of high vacuum systems. Areas of applications may include high energy physics, analytical instruments, laser production, ion implantation, mass spectrometry, or PVD. The 943 digital controller features two standard independent relay set points, which allows you to confidently control your process. Adjust the set points from the front panel while viewing the display. Red LEDs indicate set point activation status.
These MKS HPS series 421 cold cathode ionization gauge controllers is microprocessor based for versatility and added functions. Color coding relates switch position to the functions of the two push button switches making most of the operations of the controller self-evident. The LCD makes possible the presentation of more information than a typical luminescent display. It is visible in a wide range of lighting situations and over a wide viewing angle.
