Abstract
A monitor device for determining end point measurements of an environmental parameter such as temperature, humidity and the like. The monitor employs a probe which consecutively measures consecutive values of such environmental parameter. Transducing means converts the measured values into an electrical signal. Clock means determines a time window which is stored in memory means. Memory means obtains a value of the span of the parameter value by determining the difference between an initial value and a selected subsequent value of the parameter. End point selection means compares the selected minimum ratio with the actual ratio within the time window set by the clock means. When the actual ratio lies within the preset minimum ratio, display means exhibits indicia representing the actual environmental parameter.
