641N | Compact Ruggedized Failsafe Ohmmeter with Self-Test Feature

The AMPTEC 641N Igniter Tester was designed for military ordnance programs as a ruggedized product that can safely measure resistance on explosive devices such as squibs, flares, and explosive bridge wire. The 641N meter is an impressive 40% lighter and significantly more intelligent than its predecessor the 640N (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 641N is among the safest and smartest products of its kind.
