High-Pressure Calorimetry Testing and Measurement Services

High-Pressure Calorimetry is a technique to measure heat flow at constant temperatures or under self-heating conditions, used to measure material's properties and physical phenomena at elevated temperatures and pressures. It is applicable to petrochemical, polymer samples, and additive manufacturing powders and is useful for coolant liquids, crude oil, and flammable liquids. Cells can be pressurized up to 400 bar for specified pressures.
