AMPTEC 640N Intrinsically Safe Igniter Tester Ohmmeter

The AMPTEC 640N Igniter Tester was designed for military ordnance programs as an Intrinsically Safe ~ruggedized product that can safely measure resistance on explosive pyrotechnical devices. With multiple safety approvals, a durable/waterproof yet compact case, self-contained DC milliammeter and test resistors, and a shielded Faraday cage design, the 640N is among the safest and most self-aware products of its kind. As a direct derivation of the 620A-4 Safety Ohmmeter, the 640N is approved by the USAF Non-Nuclear Munitions Safety Board for usage on all non-nuclear munitions, and independently certified to meet Mil. Std. 810 Mtd. 511 for its Intrinsically Safe design for usage in fuel-ladened environments.

AMPTEC 640N Intrinsically Safe Igniter Tester Ohmmeter

AMPTEC’s 640N is a 4-wire Kelvin Intrinsically Safe ~ Fail-Safe Digital Ohmmeter which has been designed to reliably provide very low test-currents for its resistance measurements. Failsafe Output Circuitry, 

The AMPTEC 620A, 630 and now the 640 Series Igniter Testers/Failsafe Ohmmeters are becoming the gold standard in the Safety Igniter Circuit Test industry, and are designed to provide extremely safe and reliable resistance testing of explosive volatile devices. Safety Approvals from various Safety Boards include, the U.S. Air Force (620A-4) for generic use on Non-Nuclear munitions and the US NAVAL ORDNANCE CENTER (630AN) and other versions pending). Devices the 640N Failsafe Ohmmeter may be used on include: fuses, squibs, igniters, explosive bolts, rocket motor squibs, automobile air-bag initiators and many other pyrotechnic devices.
