New At AVS 2015: DIGIVAC—wants your feedback on New Vacuum Technology coming to the market—a prototype is available for viewing and discussion at booth #622, October 18th-23rd, during AVS at the San Jose Convention Center.
People working with high vacuum are met with 2 problems:
1. The vacuum region from 1x10-5 to 1x10-7 Torr requires devices that employ indirect measurement technology such as cold and hot cathode gauges with typical accuracies of +/- 30%, which is considered acceptable. An accuracy range of better than +/- 5% is considered almost unattainable with current measurement technologies
2. Many academic and industrial processes use a mixture of gasses other than Nitrogen, without establishing an appropriate correction factor, the accuracy of all indirect gauges is compromised
Since most indirect measurement gauges are calibrated in Nitrogen, measuring pressures of different gases with different properties requires a correction factor. Gas correction factors are often based on a particular gas. Therefore, applying gas correction factors for a mixture of known or unknown gases becomes more challenging. This is especially true if the ratio of gasses changes throughout the process.
If there was a solution to these problems, would you want to learn more? Please consider giving us your feedback on a new digital vacuum gauge that avoids these problems by completing a short survey.
