The 620A-4 Igniter Circuit Tester & Fail-Safe Ohmmeter The gold standard in ultra-safe resistance testing. The 620A-4 Igniter Tester is a portable digital ohmmeter specifically designed for ultrasafe resistance testing on explosive devices. Approved by the USAF Non-nuclear Munitions Safety Board and compatible with our RS232C Interface (OP-232), this product is the safest and easiest to use in its field. Now thanks to our ISO 9001:2015 certification, you can also be confident that you’re receiving the highest quality instrumentation available. The AMPTEC 620A-4 offers fail-safe current limiting resistor network circuitry to ensure that instrument test currents cannot exceed 8 mA. In the unlikely event of a component failure, the output current limiting network would still be in effect. If the 620A-4 had an electrical fault, it offers the life-saving advantage of failing safely. The 620A-4 leads a lineage of intrinsically safe igniter circuit testers in the 620 Series product line, enabling you to take high-accuracy resistance measurements across virtually any range from 2 Ω to 20 MΩ. Every AMPTEC product is proudly made from start to finish in the USA and comes with a one-year warranty, plus an N.I.S.T calibration certificate with data at no extra co
