620A-4 | Digital Failsafe Ohmmeter
The 620A-4 Igniter Tester is a failsafe and portable digital ohmmeter specifically designed for ultra-safe resistance testing on squibs, flares, bridge-wire, and other explosive devices. The 620A-4 safety ohmmeter has been 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 usage in fuel-filled environments. Due to its intense self-safety design and numerous certifications, the 620A-4 failsafe ohmmeter is the industry standard for military programs in need of igniter testing.
