Abstract
A method and apparatus are described for accurately estimating the concentration of residual fumigant in a commodity in a fumigation chamber from the rate of decline in concentration of fumigant in the exhaust air stream during the aeration period following fumigation. Because the method is nondestructive and lends itself to automation, it us useful for commercial application.
