small pans are placed on the separate blocks (Figure 11.17). Each block is provided with a separate
heater and thermocouple with feedback to the heaters so that the power supply can be varied as


necessary to ensure that ∆T = 0 at all times as the temperature is raised overall. A thermogram is then
generated by monitoring the difference in power supplied to
