The AMPTEC 620RK failsafe ohmmeter was specifically designed for ultra-safe testing on squibs, flares, bridge-wire, and other explosive devices. The 620RK meets mid-range resistance requirements, and comes standard with an (OP-232) RS232C interface, and (OP-247) optically isolated power. This product was derived from the USAF Non-Nuclear Munitions Safety Board approved AMPTEC 620A-4 meter – thus creating a product line that is the industry standard in igniter testing.
