Abstract
A method and device for continuously analyzing, retaining and periodically displaying the concentration of a selected component in an emission gas from a vapor recovery unit. A timing device is provided to periodically display the average concentration of the component in the off gas and the concentration is continuously monitored and supplied to first and second level alarms to be actuated at selected concentrations of the component where when the concentration reaches the first level the concentration is displayed and where if the concentration reaches the second level the vapor recovery unit may be shut down.
