The invention is a handheld device that is adapted for wireless communication with an electronic monitoring device, and includes a control unit and dedicated operating system configured to analyze data retrieved from a data logger and determine if the electronic monitoring device has been exposed to an environmental condition exceeding a predetermined threshold. In some embodiments, the handheld device may be configured to generate a sensory output if the data indicates that the predetermined threshold may have been exceeded. The handheld device may also have an associated memory component configured to store the retrieved data. In some embodiments, the reader may also be configured to calculate the remaining shelf-life of an item that is in a monitoring relationship with the electronic monitoring device.
