AMPTEC 641RS Intrinsically Safe In-Circuit Igniter Tester Ohmmeter

AMPTEC’s 641RS Intrinsically Safe – Fail-Safe Igniter Tester Ohmmeter is specifically designed for the ultra-safe in-circuit testing on squibs, flares, bridge-wire, and other explosive pyrotechnic devices. The 641RS offers 8-Ranges from 2low-range to high-range resistance measurement solutions while incorporating a fail-safe current limiting resistor network circuitry to ensure test currents cannot exceed 8 mA. In the unlikely event of a component failure, the output current limiting network would still be in effect. If in the remote unlikely event, the 641RS had an electrical fault, it offers life-saving safety.

The AMPTEC 641RS Intrinsically Safe Fail-Safe Igniter Tester was designed for US Military Ordnance Programs as a compact Ruggedized In-Circuit Igniter Tester Ohmmeter that can safely measure in-circuit resistance on a variety of Pyrotechnic devices. AMPTEC’s 641RS Igniter Tester 8-Range Ohmmeter is significantly more intelligent than most others with the introduction of the novel self-test function. With multiple safety approvals, a durable/waterproof yet compact case, standard accuracy Test Resistors (the self-test feature), a shielded Faraday cage design for noise suppression, the AMPTEC 641RS is the leader for the safest and smartest products of its kind. The design incorporates a 4-wire Kelvin lead-wire resistance compensation feature.

The 641RS‘s 7-Ohmic ranges cover from a 2Ω Full Scale range on the low end with 100µΩ resolution to 20MΩ with 1KΩ resolution on the high range.   The full-scale display is 19999 LEDs thereby providing 100µΩ resolution on the 2Ω range. Attributed to its proven and documented intense Self-Safety design along with numerous safety certifications, the  AMPTEC 641N Igniter In-Circuit Tester is one of the AMPTEC gold standards for Military, Aircraft and Aerospace programs requiring Ultra-Safe Igniter Circuitry Testing.
