Description
            The Perkin Elmer TGA7 Thermogravimetric Analyzer measures weight changes in sample materials as a function of temperature or time.  A sensitive microbalance is used, featuring a null balance design that compensates for weight changes in the sample.  The amount of current needed to maintain the system in the "null" state is directly proportional to the weight change of the sample.
