From the project
A modern, low-cost universal controller for hot-cathode ionization vacuum gauges. (WIP)
A modern, low-cost universal controller for hot-cathode ionization vacuum gauges.
Many physics experiments require a good vacuum and therefore tools to diagnose vacuum-related problems. Ionization gauges provide a way to measure pressures in the medium to ultra-high vacuum regimes.
While the gauges themselves can be procured quite easily, the controller situation is more problematic. Existing commercial and DIY solutions have one or more of the following issues:
