The Datapaq Paqfile Viewer is a free software download that allows Datapaq temperature profiles ("Paqfiles") produced by the Tracker or Insight software packages to be viewed. The Paqfile Viewer provides a graphical display of a paqfile, plotting temperature against time, and lets the user view measured temperature data. In addition, the software analyzes maximum/minimum temperature for each thermocouple, calculates time above or below a specified threshold temperature and produces a single page report containing the graph and analysis calculations.
