Copper Crusher Gauge
Copper crusher gauges and measuring elements for interior ballistic high-pressure measurement up to 8500 bar — manufactured from C10200 copper (≥ 99.9 %) with the highest precision in Germany.
Description
The Copper Crusher Gauge — internationally known under this name — is a classic device for measuring the maximum gas pressure in the chamber of firearms and ballistic systems. It is used primarily for safety verification and performance determination of ammunition in the interior ballistic range.
Thanks to its robustness and simplicity, the copper crusher method has become a standard procedure — from single-shot testing to series testing in ammunition production. Manufacturing is carried out by our subsidiary pecnolet GmbH, based in Wiesloch, Germany — giving us direct access to production quality at all times.
Typical applications
- Ammunition testing — Determination of peak gas pressure to comply with safety standards under NATO, STANAG, CIP, SAAMI and other norms
- Large-caliber weapons — Routine pressure verification for artillery and heavy weapon systems
- Quality control — Comparison of powder batches and propellants during production
