Closed Vessels NV series

Closed Vessels NV series

The Closed Vessels NV Series (Small Scale Manometric Bombs) is used for measuring, with constant volume conditions, the pressure profile of a burning sample not only powders and compact energetic materials but also igniters and electrical squibs-in a small closed vessel.



The typical internal volume range of the NV Series is 3, 5, 10 or 20 ccm with maximum pressure of up to 5000 bars. Maximum pressure, burning time, ignition delay time, pressure gradient, pressure rise time, or burning rate may be acquired from the test records. The Closed Vessels NV series is designed for quality control, safety testing, research and development of energetic materials including primary explosives, propellants and pyrotechnic substances.

The Closed Vessels NV Series’s typical application is found in the testing of electric initiators like squibs, fuses, etc., as well as the determination of ballistic properties of small-caliber gun powders. The Closed Vessels NV series is so versatile it is found in all manner of explosive and automotive, research and development and quality control laboratories.
