Home | Products | Explosive Bridge Wire Testing | 620MG | Digital Failsafe Ohmmeter with Diode Test Capability

The AMPTEC 620MG failsafe ohmmeter was specifically designed for ultra-safe testing on squibs, flares, bridge-wire, and other explosive devices. The 620MG meets a wide-range of resistance requirements, and comes standard with an (OP-232) RS232C interface, (OP-247) optically isolated power, an autorange feature, and a diode test capability. 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.
