Abstract
Calibration gases are an essential element of pollution measurement. Their importance is emphasized because calibration errors are translated directly to the measured data.
The concept of a calibration gas department responsible for filling the needs of all exhaust emission test facilities within an organization is a proven method for improving accuracy and precision, reducing test variability and assuring complaince with the law.
Centralized handling of zero and span gases for multiple test sites within a facility is cost effective. In our case, installation costs were paid back in less than a year from the savings in product cost, cylinder rental and material handling.
