There are three valid techniques used to build calorimeters, Heat Flow, Temperature Rise and Power Compensation. TA Instruments understands each of these measurement methods and manufactures instruments using all three techniques. TA offers a broad range of calorimeters - - from power compensation calorimeters for looking at biopolymers in dilute solution to online temperature rise calorimeters used to solve production problems in the blow molded plastics industry.
