  • Method for measuring chemical emissions
    Patent number: 6553810
    Abstract: A test device for measuring chemical emissions to the atmosphere from a leaking component that includes a housing containing an air mover for drawing ambient air directly into the housing. The air mover is capable of operating at a high flow rate and a low flow rate depending upon a switch state or valve position. A detector for detecting the presence of a chemical emission is positioned within the housing as well as a calculator for measuring the concentration of the chemical emission. Air is drawn directly into a housing at a low flow rate in a survey mode and once a leak is detected air is drawn directly into the housing at a high flow rate in a quantification mode. During the quantification mode the calculator determines a leak rate from the leaking component or alternatively indicates that the calculated leak rate is unreliable.
