Yes, right now, present day. An e-chem sensor can check sensor function and instrument flow path without bottled gas or a regulator. Flow path is checked using a worker’s exhaled breath. Time between full calibrations can be extended via the capability to automatically adjust sensor output within acceptable parameters.
This gas detection sensor technology is available now—read about it in Gas Processing magazine, courtesy of author Towner Scheffler, MSOL, Ph.D. Dr. Scheffler holds more than 15 MSA gas sensing technology-related patents and contributes to research and development of electrochemical, spectroscopic and ionizing sensing technology.
