AMPTEC 641N Intrinsically Safe In-Circuit Igniter Tester Ohmmeter

AMPTEC 641N Intrinsically Safe Igniter Tester 7-Range Ohmmeter w/Self-Test Feature

AMPTEC’s 641N Intrinsically Safe – Failsafe Igniter Tester Ohmmeter is specifically designed for ultra-safe in-circuit testing on squibs, flares, bridge-wire, and other explosive pyrotechnic devices. The 641N offers 7-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 641N had an electrical fault, it offers the life saving safety..

The AMPTEC 641N 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 641N Igniter Tester 7-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 641N is the leader for the safest and smartest products of its kind. The design features 4-wire Kelvin lead resistance compensation.
