Portable megohmmeter 620ES

4-wirefor the aeronautical industry

The AMPTEC 620ES failsafe ohmmeter was specifically designed for ultra-safe testing on squibs, flares, bridge-wire, and other explosive devices. The 620ES meets mid-range resistance requirements and offers a fail-safe current limiting resistor network circuitry to insure test currents cannot exceed 8 mA. Capable of making highly accurate resistance measurements from 2 Ω to 200 KΩ, this ohmmeter has a proven track record of durability: with 20+ year old units still being used in the field today. 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. The 620ES Igniter Tester is a portable digital ohmmeter specifically designed for ultra-safe 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 620ES 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 620ES had an electrical fault, it offers the life-saving advantage of failing safely. The 620ES is part of 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.
