620VN | Wide Range Digital Failsafe Igniter Tester

The AMPTEC 620VN failsafe ohmmeter was specifically designed for ultra-safe testing on squibs, flares, bridge-wire, and other explosive devices. The 620VN meets wide-range resistance requirements and offers a fail-safe current limiting resistor network circuitry to insure test currents cannot exceed 8 mA. This product also comes standard with an RS232C Interface that allows the tester to communicate with a computer. 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.
