Description

The program collects temperature data from a Parr 6772 Calorimetric Thermometer using a RS232/USB adapter connected to the printer port of the device.
The data is graphed versus time as it is acquired.
When acquisition is completed the time/temperature data is saved and analyzed.
The analysis is conducted by using 4 cursors. Two are used to define the pre-reaction period and two are used to define the post reaction period.
The points in the pre-reaction and post-reaction periods are fit to linear functions.

The difference between the pre-reaction and post-reaction fits at the mid-point between the end of the pre-reaction period and the start of the post-reaction period is Delta-T.

The program can also be used to analyze previously acquired data.
