The following parameters were determined; <br />• Detection Accuracy - The measure of sensor response to the presence of liquids. <br />• Response Time - Amount of time the detector must be exposed to liquid before it responds. <br />• Recovery Time (') - Amount of time that passes before the detector returns to its baseline reading <br />after the test liquid is removed. <br />• Lower Detection Limit - The smallest liquid concentration that the detector can reliably detect. <br />• Minimum Sensitive Height - The minimum sensor length required to be in contact with the liquid product <br />to cause sensor activation. <br />• Product Activation Height - The height of liquid to cause sensor activation. <br />• Specificity - Indicates the level of response, of the detector, to several different liquids. <br />After a Sensor alarmed, the sensor was allowed to air dry per manufacturer's instructions. <br />Carnegie Mellon Research Institute 4400 Fifth Ave. Pittsburgh, PA 15213 <br />
