This unique Calorimeter is designed to measure the heat of detonation to aid research in the area of high explosives performance. Sample sizes of up to 25 g can be accommodated in the specially designed spherical combustion chamber.

Parr Instrument Company’s heat of detonation calorimeter accepts up to a 25 g high explosive charge with a nominal total energy release per charge of ~160 kJ. The detonation is initiated using a small commercial EBW style detonator incorporating 80 mg of PETN and 450 mg of RDX with a binder. Detonators are fired using a one-microfarad – 4000 V capacitance discharge firing set. A complete calorimetric measurement can be made in a few hours with a precision of several tenths of a percent.
