Dupont 943 Thermomechanical Analyzer
ITEM: 28950 In Stock
The Dupont 943 Thermomechanical Analyzer P/N 915001.901 is a plug-in module that can be used with any of the Du Pont Thermal Analyzer contra I consoles to make up a system for collecting and reporting data from thermal experiments. The system measures changes in sample properties resulting from changes in three experimental variables: temperature, atmosphere, and time.
In the Dupont 943 Thermomechanical Analyzer P/N 915001.901, a sample, which can be formed as a plug, film, powder, or fiber, is compressed or held in tension by a probe assembly. Movement of the probe is translated electrically by a linear variable differential transformer (LYDT) attached to the probe, into a signal that appears on the Y axis of the plotter.
The Dupont 943 Thermomechanical Analyzer P/N 915001.901 uses interchangeable probes that allow the user to make a number of important measurements, including softening point, tensile modulus, compression modulus, glass transition, and expansion coefficient.
