When it comes to safety, time is extremely critical. In the areas in a cement plant where explosions or self-ignition of coal are a potential hazard, a fast and reliable measurement of CO or oxygen is necessary. Traditional continuous gas analyzers have a sampling system that results in a significant time delay.
