Home | Products | Explosive Bridge Wire Testing | 641RS | Compact Ruggedized Failsafe Igniter Tester with Self-Test Feature

The AMPTEC 641RS Igniter Tester was designed for military ordnance programs as a compact ruggedized product that can safely measure resistance on explosive devices. The 641RS meter is an impressive 40% lighter and significantly more intelligent than its predecessor the 640 Series (thanks to the introduction of the self-test function). With multiple safety approvals, a durable/waterproof yet compact case, self-contained DC milliammeter and test resistors, a shielded Faraday cage design, and the new self-test feature, the 641RS is among the safest and smartest products of its kind.
