Abstract: A handheld portable apparatus adapted for retrieval, display and transfer of data in association with data recording systems such as are common in the container transport industry. A control and display module affords user interaction. Operable connection of a data recording system device initiates data collection, processing operations, visual display, alerts and storage of data sets, allowing selected communication with remote systems.

Abstract: A thermograph system and precision temperature sensor wherein a continuous running default time-temperature recording is made and available for subsequent computer readout and printout, and a simultaneous select time duration recording that is started and stopped for documenting time periods during which critical temperatures are involved, characterized by LCD instant readout of the highest and lowest F° or C° temperatures throughout a selected duration recording or said default recording, with a Driver-receiver for compatible voltage differential data transfer to and from a personal computer for downloading of select-duration and alternately default time and temperature recording data.
