The Phi-TEC I is a computer-controlled adiabatic calorimeter that can be used to determine the heat evolved and pressure developed during an uncontrolled exothermic runaway reaction. It is the modern alternative to the classic ""ARC"" developed by Dow Chemicals.

The system is completely computer controlled and features a range of high-pressure test cells, magnetic stirring and pressure and temperature logging. Standard Pre-programmed Tests make runs quick and efficient and simple standard test cells keep consumable costs to a minimum.
